New Player Guide

This isn't meant to be a complete guide to everything about BTA. It's meant to provide training wheels for new players as they try to do sick jumps off the learning curve and a helmet for when that inevitably goes wrong.

Differences from Vanilla

1. Permanent Evasion: Evasion can no longer be reduced by firing at targets. This applies to both the player and the opfor. Only sensor lock and stability loss reduce evasion, though there are many more options to increase your accuracy.
2. Sprinting: You can fire after sprinting, at a greater negative.
3. Pilot Behaviours: Pilots can eject and have dynamic injuries with different effects, including bleedouts (this kills the pilot... eventually). They can also be sent into battle with injuries, with obvious risks.
4. Positioning: Height matters, conferring a bonus to hit target below you and a penalty to hit targets higher up than you.
5. Size Delta: Heavier targets have difficulty hitting smaller targets and smaller targets have a bonus to hit larger ones. This confers a +/- per 15 ton difference, to a maximum of +/- 5
6. Precision Strikes: Precision Strikes no longer allow targeting of individual limbs, instead conferring a flat bonus to hit. Called shots can be re-enabled by a rank 8 Gunnery skill or certain Fire Control Systems.
7. Melee: A great many changes, but in brief: kicking and charging are now options. All weapons that are not AOE or that have a minimum range can fire in melee, but are limited by where on the mech they are. Weapons on arms cannot be used when punching, weapons on the legs cannot be used while kicking (yes, that's a thing) and no weapons fire on a charge.
8. ECM: ECM no longer makes you "invisible" and instead provides flat bonuses in an area. Alongside Guardian ECM there are a variety of options that confer defense, view range and sensor bonuses. These are those circles you will see under some mechs.
9. Mech Engineer: There are many, MANY more options available to you. Read the text carefully, but in brief:
   1. XL engines free up weight but kill the mech if a side torso is lost
   2. Core sizes determine how fast you can go and how many internal or required external heat sinks you need. Small engines require you to mount external heatsinks (but are free, weight-wise).
   3. Heat sink kits of various types must match the heat sinks you are trying to use
   4. Armor types have weight and armor related effects but cost "dynamic slots" that are redistributed automatically around the mech
10. Reworked skills: See them here.
11. Vehicles are scary, but have significant weak spots that can be exploited. There will be an entire section dedicated to this, don't worry.

Starting a New Career

Quick prep: on a new install, load the Skirmish mech bay - this is required to load all assets properly.

Difficulty settings

There are a few bits to your starting settings that can ease your journey. I recommend these because as much as many people may want a tougher economic game, that often gets in the way of really coming to grips with the game's changed tactics and strategies - you can't figure out how you want to use heavies if you literally can never afford to get there. You can always change these as you go:

1. Reduced Argo costs: does what it says on the tin. Helpful for getting the basics out of the way early like increased drop size, mech bays and medic/moral points
2. Friendly Fire: Strongly recommended against until you understand how godawful your initial accuracy is. You will absolutely, 100% core your first XL engined mech by accident.
3. Starting Planet: Affects what you're going to start with and what you're likely to fight. Safe bets are Steiner and Davion but any of the "standard" starts are good (except, arguably, for Arano, which is slightly harder). Please note the starts that say "Hard" are not fucking around.
4. Parts for Assembly: 3-5 is sane. Anything beyond that and you're going to be depriving yourself of the chance to try out rarer mechs.
5. Mech Recovery: chance to reclaim the ruined metal corpse of your mech. Leave as standard.
6. Contract/Salvage: Self-explanatory. Leave as standard.
7. Commander Experience: Worthwhile to bump up so you have a ringer with good accuracy. Drop it down in later careers
8. Advanced Mechwarriors: The rate at which you see those crazy pilots you can never hire because your rep is too low.
9. Pilots per system: Self-explanatory. Leave as standard.
10. Mechwarrior Progression/Exponent/Multiplier: Complicated math. Leaving it as standard is fine.
11. Lethality: This is lethality in regards to headshots and nothing else. Leave as normal.
12. Starting money: Definitely worth bumping up as a newbie.
13. Mechbay C-bills: Complicated math. Leaving it as standard is fine.
14. Shop Selling Prices/Scrap Return: I actually recommend turning scrap as low as it can go and bumping selling prices up a bit. This encourages you to be careful and strategic in what you salvage and build - scrapping stuff turns into a real option of last resort. "Oh crap I'm about to go bankrupt" sort of things.
15. Mech Maintenance: Large cost increase. Leave as Easy.

Commander Generation

There are a few new things going on here. The first two choices for your background change your default skills. This is largely fluff. The third, however, confers significant bonuses.

1. Pioneering Comrades: Grants BTA crew. Strong crew with unique skills. Kinda OP, but a very good choice starting out. Also, pay your respects. Some are more difficult to use than others. They have special skills, found in their bios and in the buffs section of the combat UI.
2. Life Savings: Does what it says on the tin. Cash money and morale.
3. Great Reputation: Increase in base MRB score. Your worst choice. You're not ready.
4. Upengined Dropship: While on the surface of it the increase in speed is minor it DOES pay out eventually in saved transport costs. Tech points are super useful early on as well.
5. Ancestral Mech: You get a free light mech based on your origin location. This drops on the third day. Note that with your Heavy Metal crate, this will put you over capacity, so be aware of that when making your choice. Also, don't... uh, don't select this option with the Deep Periphery ancestry.
6. Radio Crowd: Another set of pilots, this time unique voice actors. See if you can recognise them! This may not seem like the best option, but when you're getting stomped, a worried whine from a creaky-voiced old man is hilariously uplifting.
7. Original Adventurers: You get the original pilots you started with, now with upgraded portraits! If you lose Dekker this time, it's on you (it's always been on you).

Your portrait options are expanded, as are your voice options. Have fun.

First Days

Note: if this is your first time loading, with the Skirmish mech bay workaround, your game will likely chug at this point. This is normal. Tough it out or save and exit if you like.

The first thing that is going to happen is that you're going to get a big ol' crate of free spare parts. You might need them. You might end up selling them. Shut up and take them. At this point, open up your mech bay and take a look at what mechs you got on generation. This might influence your selection skills. For example, if you have a mech with an active probe, you might forego a second pilot with Sensor Lock/Target Prediction.

Which is a nice segue into your next action, which is evaluating your pilots. As stated, you should aim to have two pilots with Sensor Lock or Target Prediction. These will be critical to your early game because your accuracy is going to be terrible. Sensor locks still stack (with each other and Target Prediction), but Target Prediction does not stack with itself. Two sensor locks are fine, two target predictions aren't great, though you can roll them sequentially for an ongoing buff. If you lack two pilots with sensor-type skills, specc your commander into one. This might seem like a waste early on, but later on in the tree Master Tactician still ain't bad and Knife Fighter is fun.

If you DO have two pilots with sensor-type skills, go nuts. Getting to piloting 6 ASAP is advisable because that +1 Evasion is love, is life. Your commander is also the only pilot who can kinda get away with low Guts, but that's going to suck regardless. There's something to be said on running high Gunnery, especially if you have extra Commander XP and you rolled a good Heavy Metal crate, so consider saving actually actioning your choices until you know the full extent of you hangar.

Advance time. On the second day, you will receive an invite to BTA Live Fire exercises. If this is your absolute first time through, go through them. If this is your nth time through having gotten stomped all thorough-like consider going through them.

Following the live exercises, the Heavy Metal crate drops. Yes, it's actually random, and has an extended drop table. If you're seeing repeated drops of the same mech, welcome to BTA! We are all helpless before the baleful eye of RNGesus.

Day three brings your Ancestral Mech if you chose one. You're almost ready to kick a mech in the crotch!

Now check out your biome. Are you on a lunar, desert or Martian world? Get the fuck off it. You have enough going on without learning new heat management. Save that for, like, month 3 or something. Go find a different world (POSSIBLY not a half-skull world - still doing testing theory that half skulls are more vehicle-prone and thereby strictly more difficult for new players). If you do decide to fly off to another world, remember to start any refits and engineering before you take off. Engineering should prioritize mechtech points and bays when you first start - once you feel more comfortable with career progression feel free to branch out. Some refits to consider: replacing any autocannons with UAC/LBX versions if you got a drop with those in them, stripping large lasers and PPCs off lightly armored mechs and replacing them with armor and smaller lasers and, if you have an SRM boat, buying inferno ammo if it's available.

Actual Advice

General Gameplay

Movement

With permanent evasion, the meta shifts towards lighter mechs that can move. Obviously Bulwark and Cover are still obscene, but lighter mechs are much, much more viable now. As a rule, sprint for max evasion pips unless you can keep a majority of them and stay in cover. 8 pips good, 6 pips and cover good, 5 pips and cover... ennnnh?

Situations where you're confident in wiping the last target may call for just moving for better accuracy, but early on, keep those pips up. You'll be safer and learn more.

Sprinting reduces your accuracy by -2 and jumping by -3. The jump penalty can be moderated by using it to take high ground, which confers a bonus based on how high you are compared to your target (and negatives for the opposite). This means that early on, you really need to get your Kenobi on and take that high ground. Take the high ground and bait the enemy towards you. At the very least equalize the heights.

Positioning continues to matter in BTA, with all the same tricks you learned in vanilla, but with a new caveat: obstructed targets get damage reduction to certain parts of their bodies. Mechs take 50% less damage to their legs when LOS is obstructed (look veeerrry closely at the spot where your targeting line changes color. See that eye? that means obstructed) and vehicles take the same to all parts, minus the turret. Quad mechs (yes, BTA has those) take 75% less damage. All of this benefits the opfor as well as yourself, so pay attention.

Shooting

A major change to shooting in BTA is the ability to change firing modes and ammo types. Click the ammo to switch between ammo types you have equipped and click the x2 or firing mode to switch between, well, firing modes. Note that weapons with rapid fire modes have jam chances that usually take over at 50% of their max firing rate. Clearing a jam is complicated math based on your Gunnery skill - when low it can feel like forever before your UAC10 clears, alas.

Speaking of UACs, note that because of refire penalties on autocannons and similar weapons, you take penalties on accuracy when firing autocannons on repeated turns. This was present in vanilla, but less accuracy variables, and vanilla's... fudging of accuracy made it really easy to ignore, aside from like, AC20s. Early on in BTA it you will likely find it useful to pause between rounds firing autocannons.

Targeting, while nerfed with the nerfing of precision strike, is still incredibly important in BTA. When you do get a called shot off, right click the mech and hover over the parts in the top drop-down to identify what gear is where. You'll eventually internalize like "what mechs have XL engines" with enough play but its useful to find out where the ammo is, so you can target or avoid the fireworks associated with those. That outline also gives you the armor and structure totals for each part, letting you determine how much fire based on your hit percentage to direct at, say, a leg that you want to lop off.

Salvage

NOTE: There are some combinations of parts-to-salvage and damaged parts that give wonky results and sometimes things just go wrong in game. All numbers provided below are based on 5 parts salvage and are verified where possible but please understand it's not an exact science 100% of the time and sometimes Unity just decides that memory sector can go fuck itself and you too.

Salvage works much like vanilla, but given all the new shiny mechs lying around, you might be tempted to try and focus on getting some that interest you. That's a sane idea.

Generally, the same ideas apply in vanilla - always take max salvage (except in duels), legging and headshots are best, and prioritize parts over gear. But there are some new elements as well.

1. The big ones are XL engines. You can blow out a side torso, which destroys the engine but you get a majority of parts.
2. In addition to kneecapping and headshotting, you have two more high-salvage options:
   1. Ejecting: basically a self-headshot, an ejected pilot with all limbs intact will result in max salvage on the mech
   2. Engine crit-out: an engine has three crit "wounds." If you manage to crit the engine three times without coring the mech, it leaves max salvage (assuming you didn't blow off any limbs). Note that sometimes you will see "CRIT X3." These count as 1 crit. Sorry, engine makes the rules, not me.
3. In cases where there are some extremely high priority pieces of gear on "offer" or where you don't have many salvage picks, you may want to prioritize gear over parts. Instead of trying to save parts, core the mech. You get 1 piece of the mech and all of its (undestroyed and not on destroyed parts) gear. If you really want to manipulate your loot pool you can pick all the arms and torsos off a mech to make sure it eventually only gives you 1 part and 0 gear.
4. You can construct mechs out of related variants - HBK-4G, HBK-4J, and HBK-4N can all be used to build a Hunchback. The one built is the one with the majority of parts. Note that some mechs may "appear" the same as others, but are in different weight classes - Centurian-9s and -10s are good examples. These cannot be used to build each other.

Dealing with Vehicles

Vehicles, in general, have elevated armor and reduced structure compared to mechs. The lighter ones also move ridiculously quickly and the heavier assault vehicles mount an absolutely withering amount of firepower.

There are several options available to you for dealing with them, however.

1. Vehicles take double damage from melee, as normal. This, plus your expanded melee options, like double kicks from the Guts tree and the sheer damage output from charging, makes for effective removal of medium and lighter vehicles.
2. Vehicles don't take heat damage, but take that damage as direct damage, doubled. Inferno SRMs, mortars and plasma weaponry as well as traditional flamers work really well here, as is trapping them in burning forests as they take damage when starting in a on-fire tile.
3. Thunder, aka FASCAM, ammo is good for trapping vehicles as they will try to avoid the mines it lays. Does reasonable damage if they don't.
4. Vehicle line of sight is limited compared to mechs - their height matters. This makes taking down assault vehicles potentially easier because of their slow speed. Stick a rock between them and your lance and sensor locks and indirect fire can ruin their day, even when they show up in 1.5 skull mission.
5. Piercing weapons are an option, but require you to boat them pretty significantly to have an effect.

In general though, the big problem people face with vehicles is prioritization. That little Packrat is absolutely irritating and when its Large Laser hits it can hurt, but it is likely a lower priority than the slower vehicles, even a junky Hunter. So long as you're properly protecting your facings, save your shots until you can safely mass enough fire to land hits through its 8 evasion + defense bonuses. A Mortar carrier with Mortar 8s? Kill that thing 'now'. Carriers, except for some laser carriers still, uh, carry the full weight of their threat from vanilla.

There's an upside to vehicles as well. They are gear piñatas. Specialty ammo types, artillery pieces and even some Angel ECM are available early on in your career from vehicles that are likely to spawn early on.
