Alien Shooter is an isometric shooter by Russian developer Sigma Team. The best way to describe the game would be, the gameplay of Serious Sam in an isometric perspective with the art sensibilities of Fallout (to some degree). Though, while that may sound great, the game lacks serious polish. Pathfinding is horrible and next to useless, even moving among normal stuff standing around in the levels can get your characters stuck for some time (while the animations of your character looks seriously bonkers).
Balance is seriously lacking as well. While the initial levels can be easily beaten, after some time the game just starts throwing monsters en mass at you. It’s pretty obvious why the developer has put the cheat codes on the official game page for Alien Shooter. Another issue is that the levels look pretty much the same, monster variety is low and the mission in each level is either kill all monster or just blow up the monster generators.
All that aside, the game manages to be entertaining of sorts. Blowing up wave after wave of monsters with your weapons and painting the floor red with their remains is just as fun as killing monster in old-school first person shooters. It’s mindless fun, sure, but fun nonetheless.
