Alien Breed: Impact manages to create a tense isometric shooter game inspired by Aliens, but is somewhat let down by controls.
This top-down shooter scores top marks for evoking the feel of being trapped on a failing spaceship infested with aliens. The decent but dark graphics, irregular save points and long missions interspersed with surges of aliens works well. However, a few things prevent this from being a totally positive review. Mostly the problem is the controls! The camera is positioned behind the player, so to move (and face) in the opposite direction, the camera must be swung around by moving the mouse to the edge of the screen. This is fine when nothing is happening, but in the thick of the action while under heavy alien assault it can mean temporarily facing away from the enemy in or to just see them properly - very annoying and often lethal. Each of the 5 missions are quite long (around an hour) and you often find yourself backtracking. Saving only occurs at certain points which means significant progress can be lost on player death - not sure if this is a bad thing or not (it certainly ramps up the tension). There is an ok story line and a co-op mode. A decent little game - not a great game, but definitely worthwhile.
Alien Breed: Impact is out on the Steam store for PC only at US$9.99. It has been bundled.
