These Worms are coming to crash your castle! Enter the world of Worms’ Forts: Under Siege, now in full 3-D! You can defend yourself from atop your mighty castles or unleash your wrath on your opponents. Crush or be crushed in the classic Worms style! Worms Forts: Under Siege! puts you in command of a team of up to four fort-dwelling worms. The game is set wacky 3D cartoon environments, and you must command your worm garrison to quickly construct defenses to maximize your strategic advantage. Direct your worms to expand your castle and seize valuable resources. Have them build weapons of mass destruction to destroy your opponents' fortifications. Test yourself against the single-player game by battling through the 20 missions, and then lay siege against your friends via hotseat, LAN, or FortNet multiplayer! Now who’s king of the castle? Prove your worth in Worms: Fort Under Siege!
