ARMA2 Combined Operations
Although not required I fiercely recommend using Zeus AI Combat Skills & AI Spotting modular by Protegimus to increase immersion and help with the stealth recognition skills of the AI.
This mission was intended to be played stealthy not run and gun, It will require patience. Large number of enemy AI may decrease performance on low spec machines (quad core Recommended).
Can be completed firing only one shot.
Bullet cameras script can be enabled and disabled via radio button.
you can select from a large number of sniper rifles from the briefing screen.
