I just bought this game for $30, and "upgrading" from Worms: Armageddon I was expecting:
- New, better interface, where I could enter my own values instead of choosing from a short list
- Slick new weapons
- Faster graphics engine, hopefully with better than 256 colors
- Several new game modes and special rules
- Improved in-game utilities (map editting)
- Exact duplicate of the W:A interface, with different logos and backgrounds
- Exact duplicate of the W:A weapon system
- Exact duplicate of the W:A engine
- One additional game style: "fort mode"
- Exact duplicate of the W:A editor
