From Worms Knowledge Base
Worms 2 is a strategy game developed by UK-based company, Team17. The engine was rewritten to support DirectX-based graphics, and Worms 2 is the first version of Worms to feature online play. It is the only Worms game not to have been released for multiple platforms.
The game was originally planned to be a simple update of the original, but Andy Davidson convinced Team17 to add new features and weapons after showing them what he'd done with Worms: The Directors Cut.
