i dunno i havent tried. You can play the co-op by yourself but i wouldnt reccomend it unless you are solid snake/rambo.
snakeplain gives me lots of stuttering and freezing. Interdiction is much better. :thumbsup: i'm sure that they will release patches to fix performance. of course the 1st release isnt going to be perfect... but it is pretty amazing the levels are very large and detailed.
the gameplay is much more team oriented. its great having 9 human players working together to take down 45 terrorists +enemy tanks/vehicals
