Worms Armageddon is a 2D artillery turn-based tactics video game developed by Team17 and part of the Worms series. The player controls a team of up to eight worms in combat against opposing teams either AI- or player-controlled, using weapons both based on real-life weapons and ones that are cartoonish. The player can customize battles, teams, and maps for near-infinite gameplay options.Originally meant to be an expansion pack to Worms 2 and initially titled Wormageddon, Worms Armageddon was released as a standalone game initially for PCs in 1999 and has since been ported to other platforms; the game was also released on Steam on 20 March 2013. The game was met with positive critic reviews, with gameplay receiving praise, and placed on several lists of the greatest games of all time.

Worms World Party is a 2D artillery turn-based tactics video game. It was developed by Team17 as the seventh game in the Worms series, and was released in 2001. It was the last 2D Worms game before the series' three-year stint in 3D, starting with Worms 3D.There was a plan to make Worms Armageddon and Worms World Party cross-compatible when Worms Armageddon reached version 4.0. Since the development of new Armageddon patches was quite slow, it would take quite a long time until that could happen.
