True to its straightforward title, Build & Extract combines two core mechanics:
programming-inspired building  and  loot-driven exfiltration.
Programmable Build, Creative Combat
Use programming logic to assemble weapon combinations. Attach modules to weapons that alter skill effects and dictate activation logic.
Don't be intimidated, it's easier and more fun than you think
Bring your custom builds into battle, defeat enemies, and claim loot and currency.
Exfiltration: Big Win or Total Loss
Reach extraction zones or defeat bosses to evacuate with all loot.
Fail? Lose every weapon/module brought into the raid—but keep in-raid currency.
Insure gear during prep phase
Stash priority loot in secure lockers mid-raid
Use extracted loot for trading or advanced upgrades
