(Written from a Production point of view)
Resident Evil: Degeneration is a game for Apple iOS devices and Nokia's N-Gage service. Initially developed by Nokia and Capcom, it is loosely based on the 2008 film, Resident Evil: Degeneration.
The game follows the over-the-shoulder Third Person concept of Resident Evil 4, along with quick action segments similar to the previously mentioned. There are many similarities to Resident Evil 4 along the way such as its use of a gun merchant; the breaking of items to obtain treasure and items, and the ability to jump through/over items such as windows and ledges.
Reloading is performed by tilting back the iOS device, while shaking is used to "shake off" Zombie attacks.
Certain cutscenes in the game are Quick-Timing Events (QTEs), and the player must tap certain parts of the device to survive. These include events such as running from explosions.
The game was released onto iOS devices on 24 April 2009. It was then modified to include a segment of the film as its opening cutscene (Version 1.01.00) on 28 June. Minor bugfixing took place on 9 July (Version 1.03.00). A free preview version - Resident Evil: Degeneration Lite - was released on 14 July, though was never updated.
