Classic shoot-em-up at its best
Right from the get go you are faced with hordes of aliens that would just love to taste your blood, fortunately they are easily disposed of with one of the many types of guns at your disposal ranging from simple handguns to futuristic cannons.
As you work you way trough the sixteen missions you can upgrade your gear at shops or if you get lucky you might find something better, though my experience is that it doesnt happen often and so you mostly rely on the shop for equipment upgrades.
One of the bad sides of this game is that you can play trough it in 4 hours give or take and thats rather short in my oppinion, im used to games giving me atleast 40 hours of gametime and here is where Alien Shooter Vengeance disappointed me a little. They do however offer a survival mode in which you can try to set the highest score holding out as long as possible against an endless stream of aliens, but that just doesnt quite cut it either.
The game has a nice storyline though be it simple, it even has an alternate ending, it does lack any cinematics but does pretty well without them nonetheless.
Overall a very good gaming experience and definately worth it.
