Manufacturer Perk[]
Weapons found in Io Black Site, not including AV or Unique weapons, have the Tei Tenga Labs manufacturer perk. This causes their damage to apply the Wither status (Reduces resistances by 50%, increases damage taken by +20%)
Branch Mission[]
On each level, a CRI assault will start anywhere from 180-240 turns after entering. Once this assault starts, a number of CRI marines and bots will spawn from the starting elevator and begin actively hunting all non-CRI non-player units on the level. Although they do not hunt you, CRI are still hostile and will still attack you if you enter their field of vision.
The goal on each level is to assist the CRI in exterminating all the demons on the level without any CRI marines dying. A prompt will show up on screen after the assault succeeds or fails. If you kill all demons on the level before the CRI assault starts, the event is cancelled for the entire branch and no more CRI will spawn. You will also receive no rewards in this case.
If the CRI assaults succeed on every level (including the Black Site Vaults) and you have killed less than 6 CRI units throughout the entire run, you will receive 2 red keycards (which will be placed near the entrance building) and the CRI Clearance, causing all non-corrupted CRI forces to become friendly to you. The CRI Clearance can be lost if you kill 2 or more non-corrupted CRI units after receiving it.
Black Site Vaults[]
The Black Site Vaults consist of an large circular outdoor island, with the entrance lift in a building on the south edge. Various enemies roam the island including one exalted kerberos pack which will drop a red keycard. The center of the circle has a lava lake with a small island accessed from the south, containing the final vault.
There is a vault building in each corner. of the island. Each vault is guarded by 4 turrets and a locked door. With the dropped keycard, 3 more need to be brought with you to access all 4 vaults, or 1 if you clear the CRI assault event. Once all 4 doors are unlocked, the central vault will also open for an additional reward.
Picking up the BFT9K in the central vault will spawn multiple fiends outside the vault. They are meant as a quick demonstration of the large AoE and destructive power of the weapon, and can be cleared easily by firing it into the crowd.
