It's fun for sure, but not without its quirks and flaws. The single player game is definetly the main strength. Its way too easy to run over your own teammates with the buggys, and there seems to be no way to turn that off. Also you score points for building walls and bunkers no matter which team you are on or where they are. I was playing a map today where my team was supposed to be on offense, capturing the final objective, and some jackass was going back through the map building useless stuff far away from the battle just to up his score. So I ran him over

Anyway, hopefully some of those problems can be patched, and the game is still really fun to play, but if you're specifically looking for a killer multiplayer shooter I'd probably go with Bf vietnam or UT2k4.
