LUKI released in the BI forums a new cooeprative mission where your objective is to clear all assigned sectors captured by CSAT units.

Quote LUKI :
Features:
• no unofficial addons are required
• debug hint which shows the number of alive OPFOR units on the map + local FPS is available for every player once the "T" key will be pressed
• patrols have set the probability of the presence, therefore after every new start of the game will be in sectors different units/groups
