The Gravis Xterminator is a programmable PC gamepad released by Advanced Gravis in 1999. Aimed at gamers who want a single controller capable of handling multiple genres, it connects via a standard 15-pin gameport and requires no keyboard passthrough. The pad features a unique proportional directional pad (PDP) that uses a ball-and-socket pivot for analog‑like precision, an 8‑way digital D‑pad, a sliding throttle, and a total of 13 buttons including two microswitched triggers on the underside. On‑board programming software lets users map keyboard commands to buttons and save multiple keysets for different games, launching directly without a special interface. Build quality is solid, with two weighted steel balls in the handles providing balance. The unit carries an unusually generous warranty: a 90‑day satisfaction guarantee and a full three‑year manufacturer warranty. Compatibility covers Windows 95 and any DOS title that supports GRIP.
