Doom RPG

The Doom RPG is a game developed for cellphones set in the Doom universe. The game was developed by Fountainhead Entertainment & Id Software and published by JAMDAT Mobile Inc. The game was released at the same time as the Doom movie in October 2005, and in the UK in November 2005.

Gameplay
The game retains many of the elements of Classic Doom, and is a first-person shooter like the original. However, the game is fundamentally different in that it is a turn-based strategy game. All combat and movement is turn-based, allowing the player time to select their responses in combat. The player turns at 90 degree angles and moves space by space. Although visually similar to the original games, there is a greater emphasis on the plot. It is very important to speak to the Scientists and access computer terminals to attain vital information in order to progress into the game, similar to Doom 3.

Many features of the original are retained, including the status bar face, sound effects and the majority of the weapons and monsters. Notably absent are the Chainsaw, Arachnotrons and Spider Mastermind. A difference from the original is that each monster is one of three levels of difficulty, and is colored to indicate this.

The game also adds several new features. New weapons include the axe and fire extinguisher which are useful in combat against certain enemies. The dogs from Wolfenstein 3D appear as a new enemy, known as Hellhounds. A dog collar allows the hell hounds to be captured and used as a shield.

Versions
Two versions of Doom RPG are currently known to exist, the older v1.0.20 and the newer 1.0.92. Version 1.0.92 has the following improvements:
 * Higher resolution textures
 * Enhanced sound effects - v1.0.20 only had a single sound effect for item pickup, v1.0.92 has multiple sound effects (eg. when firing different weapons)
 * View takes up the entire width of the screen, rather than being contained within a small window.
 * Improved particle effects

These release versions correspond with releases for different performance levels of cell phone technology.
