GTFO: ALT R2B1 - Sacrifice

Next step down from R2A1 is basically the introduction to blood doors and making giant strikers more common. It's a simple task: just open up the forward extraction spot which you will find just by going North all the time. This was our loadout:

Me: Pistol/Revolver/Cfoam/Spear
DL: DMR/Sniper Rifle/Mines/Hammer
Jim: PDW/Machine Gun/Sniper Sentry/Hammer
[Bot]: Hel Revolver/Machinegun/Biotracker/Hammer

Now's a good time to recap how to stealth kill giants: stack up behind solo sleeping giants and each call out a unique limb on the target. Swing a fully charged melee at the same time and your goal is to break the limb you called out as that forces the giant to stagger. Hitting the nape and destroying the head is always a good idea, as that deals significantly more damage. Note: if you brought clubs and knives, this is probably going to be tougher! For groups of big guys, clear everything else, shut the doors to kill the noise and snipe them.

Clear your drop zone of regulars and you'll find the first blood door. A mine pointed towards the door is better than one across, but either way there will still be scum that you will need to shoot after. Make use of the shelf cover provided when those spiky head hybrids come out. They can shoot a lot, but cover negates their greatest strength.

Beyond that is a big zone with giant sleepers and 4 security doors (other than the one you just used to enter). In the SE is an optional "supply closet" we didn't bother opening as it would just complicate things, then two more blood doors to the East and West, and a locked Apex door to the North. The key card is behind one of the blood doors so ping it, then prep with a mine (ours was to the East) and shoot the left overs from cover again.

Inside is a scout which DL sniped, and the key card to Apex CLASS VII alarm! To setup for this, we shut all the doors we could and DL mined all the immediate ones and the ones one step away while I cfoamed all the immediate ones and used the remaining cfoam in a cone in front of Jim's sniper sentry positioned at the Eastern blood door (because that's what we opened) facing towards the Apex door.

This is one of those "fight well" situations, but remember to do circles too! The [bot] on biotracker is amazing at letting you know which side to pay attention to as the swarm came from both East and South for us. Opening the Apex door triggers an extraction alarm so combat mine and rush and hold the extract spot as a wave of giants comes after you. DL is great with the sniper rifle and really smashed them here, though with that gun being 100% full with 8 shots it meant donating a lot of ammo kits to him, which balanced out my excess of ammo with the twin pistols. Everything worked well, and we GTFO of there. :)
