As the name suggests, it's inspired by the movie TRON. Or more exactly, by all the games that where inspired by the movie TRON. You steer a futuristic bike, called lightcycle. Combat takes place in a rectangular arena. Your bike leaves a trail behind, which is like a wall. The goal is to force the other players to drive into a wall. The winner is the last player alive.
Our Review: glTron is pretty basic stuff and manages to capture the retro feel of those Tron-inspiring games, right down to the graphics and controls. Not particularly challenging but good for nostalgia's sake.
