extensive sp mission/campaign and bonus missions, trust me the sp will take a long time, u gotta usually go on foot, so far in just 3 missions i have ran over 10 clicks.(10 km)
also has coop/dm style mp
no powerups, healthpacks, or anything, u got a fatal wound u are dead. u can try to heal chances are ull bleed to death b4 u do it.
trust me its FUN, its the best military fps simulator iv seen(better then aa3, except no annoying training, u go right into action, and chances are u will die, there is no easy mode,and normal mode is harder then any other games insane mode. enjoy!
