The Worms series' two 3D entries, Worms 3D and Worms 4: Mayhem, are being revamped for re-release in Worms Ultimate Mayhem, developer Team 17 Software announced today. Headed to PC, Xbox 360, and PlayStation 3, the downloadable double-pack promises "more single player missions, more puzzles, more customization, more worms!"

Along with 60 single-player missions, it'll pack multiplayer offerings including online play for up to four.

Head of design John Dennis explained in the announcement that Team 17 has "taken the opportunity to add high-definition sparkle to the visuals and make a raft of improvements and extra content as suggested by fans of the original titles: from vastly improved camera functionality and voice-acted mission intro sequences, to all-new challenges and multiplayer maps."

Worms 3D took the turn-based shooting series from its traditional side-on 2D plane into full 3D-o-vision in 2003, released for PC, original Xbox, PS2 and Gamecube. 2005's Worms 4 continued the 3D stylings, but series returned to the classic 2D plane after that.

Worms Ultimate Mayhem will be released via Steam, Xbox Live Arcade, and PlayStation Network "later in 2011." How much will it cost? That's for Team 17 to know, and for you to... not know yet.
