Crysis multiplayer main purpose is to admire the gfx.
The multi isn't bad, it's just not exactly awesome. You capture research point, keep them until your team has enough research done to get the kickass weapon, once that's done the other team is pretty much losing.
Then it's all a matter of nuking the other team base until you win.
Average multi, better than CS:S for me (never was a huge fan of CSS) but not better than TF2.
