RedShift (US$1.99) is a tense game that simulates a situation of trying to stop a power facility from exploding. One gets the feel of some action movies where a clock is counting down to the inevitable, but hopefully preventable detonation.
The game features side-scrolling game play with excellent graphics and sound effects. As time moves on, the power plant gets more and more unstable. Your job is to deploy firefighting gear and stop the core of the plant from exploding by flipping override switches. A small map of the facility is displayed in the upper-left part of the screen, and then you are off to the races to explore the plant, dodge the fires that are burning, and get the equipment you need to stop the explosion.
