In the sci-fi-themed Razor Salvation, the player is given command of the dropship Salvation, and the task is to rescue Earth's inhabitants while protecting yourself and the planet from the bad guys, namely pesky aliens and hungry zombies. While blasting the enemies into oblivion, the player will be treated to eye-pleasing graphics, detailed three-dimensional models, and real-time lighting effects.
Sumioni is a fantasy game with a hint of mythology in it. The player controls an the ink demon Sumioni, and the goal is to (you named it) save the world from those who want to see it crumble. It is worth noting that the game character is controlled by performing various gestures. Or as the description puts it: "Your finger becomes the brush as you perform various ink attacks by drawing directly on the touch screen." Of course, pretty graphics and visual effects are in stock.
Razor Salvation is priced at $1.99, while Sumioni will set you back $12.83. Feel free to check them out by following the links below.
