Time Crisis

Time Crisis is a video game initially available in arcades (ports?). A first-person gun game similar to Virtua Cop, its distinguishing feature was the presence of a foot pedal that controlled whether the player's character ducked behind cover (and was thus invulnerable but unable to shoot) or was in a standing position (and could thus attack but was vulnerable). A countdown clock, recharged by clearing an area of "bad guys", forces the player to take risks and stay up and vulnerable most of the time.

A two-player sequel, imaginatively titled Time Crisis II, was also produced.
