Crusader: No Regret

Crusader: No Regret is an isometric action game. Nominally a sequel to 1995's Crusader: No Remorse, it is considered both by critics and by the game director more akin to a stand-alone expansion pack. Mechanically similar to No Remorse, it features new levels, enemies and weapons. Set immediately after the events of No Remorse, No Regret chronicles the further adventures of the Silencer, a supersoldier-turned-resistance-fighter in a dystopian 22nd century. (wikipedia.org)
