This game seems to have everything going for it. It has an alien invasion, destroyed cityscapes, big guns, and Tegra optimization. By all rights, Razor Salvation should be a killer game. This title isn't free and it's a big download, so you should know what you're getting into. Let's see if it's worth your time.
The premise of Razor Salvation is epic, but poorly explored. The gist of it is that aliens have invaded Earth, and you have to land your dropship in various locations to save as many humans as possible. As you progress, more of the background regarding the Xenos invasion and the infected human population is revealed.
