And no conserving ammo when going full auto - It automatically uses up 1 bar of ammo. Take your chances, pay the price, no refunds.
I thought the same when I saw the rule. It's an oxymoron "going full auto to conserve ammo", to the point I still believe it's a typo.
I've toying with a similar rule: If you declare full auto, you can't conserve ammo and 1st Burst rolls for ammo as normal... 2nd Burst depletes ammo on [Facehug] or [Success] results... 3rd Burst also depletes ammo on [Success] or [Facehug] results, but always a minimum of 1.
I also suggested creating "supply dice", easily differentiable from the others, just for clarity and speed (for example: rolling the attack, stress, and ammo supply simultaneously).
Stage VI Xenos could also benefit from increased armor and health, specially now that PCs can
TRIPLE their rate of fire with automatic weapons, even considering that targets are able to dodge now. Most military weapons will simply ignore armor 2 or lower ratings, thanks to armor piercing ammunition and the 'weak spot' rule. It may work for drones or warriors (
You too!! you want some of this?!!) but it's pretty anticlimatic for those which are supposed to be the 'Final Bosses'. A medium fix, in addition to tweaking some numbers, could be declaring that certain Xenos or targets (like the Queen, or the Crusher, or a bulkhead) simply "have no weak spots".
The 'weak spot' rule is the equivalent of a guaranteed +1 damage just by trading 2 dice. And also enables to breach the armor of some targets you normally wouldn't be able to. You still have to hit, sure, but my impression is that it's a bit too much of a 'cost effective' deal for just 2 dice. Someone else will do the maths, probably.
And also, in other order of things, I find strange rolling to determine your 'Serious injury' AFTER RECOVERING from the incapacitated condition. I mean, when incapacitated, you can raise for 'last stand' doing again actions normally, even firing at/sprinting from a Xeno, or climbing a ladder... Just to discover some minutes later that you had a broken arm or a broken leg. IMO, The stamina roll to see if you get a serious injury should be done as soon as you get the incapacitated condition, since the results from a potential injury could determine penalties to skill rolls/movement while 'Last standing'.
