I played ARMA II at Sunday. Interesting enough, when I'm absolutely free no Snake on horizon, and when I'm busy he's always there asking me to play with him.
Anyway, there was 70+ people online and we played co-op, some mission like a D-day, landing on island then kill everything... And, I was running behind other guys, always behind, playing safe. So, at the end of the mission my platoon lost leader, lost his helping hand, and few more guys.
I survived the war without any kill. Mostly laying on ground and hiding while others were dying.
I call that kind of play: Thief, deadly shadows! XD
