Isolani is a first-person shooter set in a future when all the stars in the galaxy have gone out, safe for one, which is being harvested by a powerful artificial intelligence called The Cluster.
To control, there's a joystick on the left of the screen to control movement and the right side of the screen to aim. Your gun will automatically fire when you have an enemy in sight.
The graphics and sound, especially the music, are excellent. Be warned, the game file is huge at 483 MB.
