From a game designing point of view, Alien Shooter is a very complete e refined experience, with nice 2d graphics (beautiful sprites and excellent use of lightening, despite the somewhat cruder main character animations), solid and outright fun game play, very good atmosphere, and a sufficiently good plot for and action (rpg?). The simple, versatile controls are very well implemented, and would be ideal with not hampered by a poor path finding algorithm. The alien spree killing is just addictive. I would love to play a third version of the game with improved character customization. This game can receive the "diablo with guns" nick-name without a derogatory meaning. A must play for isometric action rpg addicted gamers.
