This is the last game in the Specimen Trilogy, this one takes place after the second game, but you play as the seventh Specimen, you're stuck in a strange dimension where there are endless waves of enemies, but you have a special power that makes you unique (it's the same power that brought you here tho) it's called "Holographic Fighter" it teleports a clone of you from another dimension to you and it fights your enemy, you also got a strange energy sword and a big fricking gun, no more talkin', get slayin' There is no end to this game, it's just infinite slaying with metal
