A multiplayer mod for the game Quake. A typical Slide map consists of a large sloping track (like a snowboarding run). At the top of the track, there is a gateway, that when passed through equips the player with a hoverboard. The player can then board down the track and try to achieve the fastest time. However, an alternative mode of play is available (usually to players who have reached the bottom of the track, but sometimes reachable from other places on the course): Instead of getting a board, the player can explore the gantries and spectator areas on foot, and find prime sniping positions to attack the racing players.

There are checkpoints that must be passed to complete the track, as well as frag powerups (kinda like Mario Kart coins), and the ability to jettison your board if you are hopelessly short of momentum. Slide was absolutely excellent, one of the best mods I've played, and it is a mystery to me why no-one ever developed a version for any subsequent FPS.
