Worms: Forts Under Siege! puts players in command of a crack team of up to four fort-dwelling worms. Set in the cartoon environments that will be very familiar to Worms fans, players direct their worm garrison to construct defenses to maximize strategic advantages, expand castles, seize valuable victory locations and of course, build massively destructive weapons to eliminate their opponents' fortifications. Players can test their mettle in a single-player game by battling through the 20 missions, or they can take on up to four friends in the frenzy of destruction that is Fort vs. Fort mode. You'll need skill, strategy and a healthy dose of Worms attitude if you want to master all 30 different weapons, and unlock the huge array of hidden maps, speech banks, missions, and challenges.
