Quiver is an interesting relic from the early 3D shooting era. Although it was released post-Doom and the engine it uses seems quite similar to the Doom engine, it is not nearly as good as the id Software classic game. It plays fairly well but doesn't quite have the polish of some of its compatriots. Although the evironments are somewhat medieval (ala Heretic/Hexen) the weaponry and enemies are both high-tech (something about aliens). Overall it's a decent game but there isn't much to commend it over its contemporary games like Doom or Duke Nukem 3D. (Note: Run QUIVERS.BAT to start the game.)
