About This Game
Worms™ Clan Wars brings friends and families together in the noble pursuit of self‐improvement, world domination and exploding sheep.
Worms™ Clan Wars is the biggest and best Worms™ game to date - more worms, larger landscapes, more dynamic water, more weapons and more customisation items than ever before. Worms™ Clan Wars is designed to take full advantage of next gen PC hardware. It features beautiful high definition 3D visuals (but still retains the classic 2D gameplay) with new lighting effects, new features to help users interact socially, exciting additions to improve the single player experience, and more of everything a Worms fan could want.
Join together with friends and other Worms™ Clan Wars players to form a fearsome team; name your clan, design your own emblem, promote other players to act as leaders and officers.
Steam Workshop integration allows you to get creative! Now you can make your worms wear exactly the outfits that you want them to. Import your own 3D objects and textures into the game using a separate tool. You can model hats, glasses, moustaches, trinkets and gravestones for your worms. You can also design your own landscapes! Proud of your creations? You can share them online, thanks to Steam Workshop!
