Worms is a 2D artillery tactical video game developed by Team17 and released in 1995. It is the first game in the Worms series of video games. It is a turn based game where a player controls a team of worms against other teams of worms that are controlled by a computer or human opponent. The aim is to use various weapons to kill the worms on the other teams and have the last surviving worm(s).

Worms is a turn-based artillery game, similar to other early games in the genre such as Scorched Earth. Each player controls a team of several worms. During the course of the game, players take turns selecting one of their worms. They then use whatever tools and weapons are available to attack and kill the opponents' worms, thereby winning the game. Worms may move around the terrain in a variety of ways, normally by walking and jumping but also by using particular tools such as the "Bungee" and "Ninja Rope", to move to otherwise inaccessible areas. Each turn is time-limited to ensure that players do not hold up the game with excessive thinking or moving. The time limit can be modified in some of the games in the Worms series.
