The Timed Mine has appeared in all of the TimeSplitters games to date. When thrown, a Timed Mine beeps for a few seconds before exploding. The Timed Mine sticks to all surfaces, including walls, ceilings, items, and even other characters. In TS2, it beeps 9 times in sync with the blinking "armed" light, followed by a tenth, blinkless double-beep alerting observers that the next thing it does will be explode.
