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.

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
