i love the singleplayer. all those tactical options! i love to play as a sneaky sob, "predator style", sneaking around and silently assassinating perimeter guards, then lure as many enemys to one place, decloak an unleash hell on them.
gameplay and map design in SP is almost perfect - yes, i believe crysis 2 spoiled me and i'm not looking forward to the next cod with it's rail-like level design and hours of sliding in and out of cover to kill thousands of enemies.
supersoldier difficulty should've been a bit higher. i'd recommend a bigger radius in which the enemy can see you cloaked. story could be more compelling, but i've seen so much worse (mw2 anymone?).
so yeah, sp-wise this could be a GOTY.
mp is a lot of fun, if your connection doesn't produce a huge amount of lag. which, unfortunately, it does for me in 9 out of 10 games.
I hope these issues will be fixed, although my hopes aren't high. but if, then this could be great.
