Doom 3: BFG Edition

BFG Edition is an updated re-release of the 2004's Doom 3, a part of Doom series.

###Changes from Doom 3
BFG Edition features improved graphics and sound, two expansion packs, and certain updates that alter the gameplay. It introduced checkpoints that automatically save the player’s progress. There are slight changes in the controls, as this version doesn’t allow the use of hotkeys. This edition also includes a copy of the original Doom in its Ultimate version.

###Plot
The plot is identical to Doom 3. The game is set on Mars in the 22nd century. The player controls a nameless space marine (nicknamed "Doomguy" by the fans). His task is to defeat the demons of Hell that invaded the Delta Labs research facility. Doom 3 features the series' trademark violence, monsters, and black humor.

###Expansion packs
BFG Edition includes two expansion packs. The Resurrection of Evil was previously released in 2005. The plot, set two years after Doom 3, follows a team that comes to a space station and discovers the hellish Artifact. This expansion introduces new weapons, such as The Grabber and the double-barreled shotgun, as well as additional multiplayer maps.

The Lost Mission is a new story expansion that was not previously released. It allows you to play as a marine from the Bravo squad that was only mentioned in the original Doom 3. The protagonist's goal is to descend into Hell to find and destroy a teleportation device that demons are going to use to invade Earth.
