Major Mayhem 1.0.4

Major Mayhem is a gleefully tongue-in-cheek rail shooter and action game. It features a customizable weapon-wielding commando on a mission to save the world and his girlfriend from the clutches of evil ninjas and such. In-app purchases are available, but there are no premium items: the purchases simply bypass an amount that could be earned through regular play.

There are enough in-game achievements, unlockables and game modes to keep most players entertained for a very long time. There's nothing extraordinarily innovative about the game - except that the tried-and-true gameplay is executed extraordinarily well. As just one sign of how the developers seem to have thought of every scenario that might impede a player's enjoyment, the game will detect low frame rates (jerky movement due to exceeding your computer's performance capacity) and ask right there if you'd like to fix the graphics quality. I can think of so many games that could have used this feature, and almost no other games that did.

Sam's protip: always keep an eye out for the appearance of the text "Rescue" in the center of the screen. The next target you see may well be a hostage! (And there is an achievement for saving a hundred in a row!)
