Doom clones. You've got good ones, like Dark Forces, and bad ones, like PO'ed. You've got ones that rise to the top, like Duke Nukem 3D, and ones that just plod knee-deep through the dead, like Universal Interactive Studios' Disruptor.
To be fair, Disruptor adds one new attack element into the mix: psionics. Basically, every few levels the hero is bestowed with a new psychic power, a psionic, that can be used to destroy the enemy. These psionic abilities are nothing to get in an uproar about, however. Think of them as additional weaponry that does its job - draining away ammo. As for the non-psionic weaponry, it's easy to come by and a pleasure to use on reasonably charismatic enemies.
Despite Disruptor's lack of ambition, first-person shooter fans will enjoy its fast-paced action. The controls are very responsive and deliver pinpoint accuracy, making use of all of the Playstation's buttons in a simple, easy-to-learn manner. There are some challenge concerns, however. Even on the Hard setting, it won't take more than a few attempts to get through the first several levels, even for players who aren't exceptionally good at first-person shooters. On the Regular level, even average players will run rings around enemy fire.
Disruptor does rise above the call of duty during its cutscenes. Despite the requisite bad acting, the story is amusing and the hero character develops a personality while learning about his new psionic implants. And the mission briefings are the stuff of genius: "You'll be facing organic enemies this time, so hunt down the phase rifle and cook 'em 'till they're well done." In the final analysis, however, Disruptor is little more than a good way to pass the time before Duke Nukem struts his stuff on the Playstation.
