- Creator Killer: Averted by Worms 4: Mayhem... but only just. Afterwards, Team 17 admitted that had Worms: Open Warfare not been as big a success as it was, the company would have been lucky to survive until the end of 2006.
- Development Hell: A 3D Worms 5 did officially enter development shortly before the release of Worms 4: Mayhem, but never progressed beyond the early planning stages, with the developers trying various ways of adapting the series' formula to 3D gameplay, but never finding anything they liked. With the series reinvigorated in the early 2010s by a new 2½D style, Team 17 finally pulled the plug on Worms 5 around 2014 and have since confirmed that there will never, ever be another fully-3D Worms game.
- Dueling Games: Armageddon vs. Hogs of War.
- Promoted Fanboy: Four members of Achievement Hunter, Geoff Ramsey, Jack Patillo, Gavin Free and Michael Jones, have lended their voices to some of the worms in Worms W.M.D.
