Grid Runner (known as Grid Run in Europe) is an action game developed by Radical Entertainment and published by Virgin Interactive Entertainment for the Sega Saturn, PlayStation, and Microsoft Windows in 1996. It is frequently described as a cross between tag and capture the flag, but the playing field is a maze-like grid which the players can manipulate to an extent. Players can either compete against each other in one-on-one matches or take on a series of AI opponents in the game's story mode. Grid Runner was first announced under the title "Eurit".
