First off, don't be fooled, this is one of the worst games you will ever play. Your first thought on booting it up may be "This looks pretty decent for an SNES game," before you realize you are three generation away from that system.
Almost everything is wrong with Target Terror. There are about 6 differnet models for enemies and about 6 for civilians, meaning you are shooting the same people over and over and over again. Why have you shot 45 women wearing the exact same leather top? Eh, don't think too hard. Aiming is ok, but reloading seems slow and finicky. Enemies swarm the screen, some hit you as soon as they walk on to the screen, some never will and there is no easy way to distinguish between the two. Sometimes you shoot enemies and they just disappear and reappear again for no other reason besides terrible frame rate. There is no hiding, no strategy beyond just hitting as many baddies as you can. You can also perform such task as shooting out windows to go into bonus games which are excruciating.
So why did I give it a decent score? Because for 9.90 (what I paid), it is fairly entertaining. Mindlessly gory, endlessly stupid, it is what you want out of a lightgun shooter. The acting is awful, to the point where it makes ALG's old "Mad Dog McCree" look like The Godfather. You'll laugh and blast your way through 10 levels and realize you've actually had a good time for the last hour, even though the joy was from watching how awful the game would get. Ghost Squad this isn't. But enjoyable, it certainly is.
