great fun, and incredibly cheap these days.
i simply loved this game, its not disasterously hard nor stupidly easy, killing soldiers is well easy but then every now and then you come across a tank, this is where the multiplayer co-op really shines, p2 quickly runs out of covetr to lob a smoke grenade, when the smoke goes up p1 gets a vantage point behind the blasted thing, the smoke clears and boom, your rocket hits it before the guy on top gets to say "al zapha kahash!".
the singleplayer is fun too, with simple, easy, yet effective commands you can have you m4 guys all doing something important at the same time, eg, covering, sniping, diverting and destroying. the squad element is revolutionary because of this, you can always have your men at full effect, even bette ron multiplayer as both of you hav 2 guys to control. the graphics are no less than satisfactory, the olny problem i found with this game, on the ps2, it got jerky once all guns were blazing and you were running round like chickens with no heads, you would often find it hard to keep this under control as them gameplay requires a lot of tactical, shooting and moving mehtids. dispite that small detail this game owns!
