Alien Breed: Impact
Judging By Their website, Alien Breed developers Team 17 haven't revamped things since the original game came out in 1991. Visuals aside, this re-imagined version of their classic semi-top-down xeno-blaster also leans heavily on the retro side of things: it's simple, fun and has a co-op mode to plough through with a buddy.
The game sees you as a gruff space engineer, one Theodore Conrad, who has to fight his way through wave after wave of alien monsters in order to reach the source of the infestation. The story is told in Max Payne-style graphic novel vignettes, but you'll never care about it. Go there, shoot aliens, interact a bit, shoot more aliens - that's all the game is and that's all it really needs to be.
Occasionally you'll find the obligatory weapons and upgrades shop - each terminal of which seems to be mysteriously intact, despite everything else being in ruins. If only Conrad's employer had made their spaceships out of that same material, they'd never have a problem with infestations.
Impacts single-player game is a solid, unspectacular blast-a-thon. The co-op side is the same thing, just harder, but there's just not enough in this mode to hold your attention for very long. Three relatively large levels provides a few hours of entertainment but there should've been more. Also, the design screams out tile-based, so why isn't there a level editor, or anything along those lines, included with the game?
At its best, Impact is an exhilarating, old school blaster that's very easy to dip in and out of. But at its worst, it's simplistic, repetitive fare with not enough to it.
