Worms: Open Warfare 2 review at IGN.

"Worms don't make fantastic soldiers in real life. In fact, they really got the short end of the stick; they get stepped on, they get eaten by birds, and they end up as bait for our luxurious fishing shenanigans. However, in the world of Worms: Open Warfare 2, worms reign supreme as the best fighters around. Actually, they seem flat-out crazy to us, and who could ever forget the screams and throaty battle cries of a gun-toting invertebrate? Team17 Software has brought the newest Worms game to the PSP, and while it carries a few faults here and there, the overall experience is quite excellent and proudly sits among the better Worms games of late."
