It has been a long time since I've revisited the invaded Mars research facility featured in id Software's 2004 shooter Doom 3, but playing the upcoming HD revamp Doom 3 BFG Edition, I felt like I hardly ever left.

While not as highly regarded as its predecessors, Doom 3 was an enjoyable (and, at the time, graphically impressive) game that garnered a fair following. For fans, Doom 3 BFG is a package filled with memories of the franchise. Along with Doom 3, its expansions, and brand new 'Lost' missions, the BFG pack includes both Doom and Doom 2.

Doom 3 BFG itself is not meant to be the original Doom 3 experience with prettier textures and 3D support. "We made some slight improvements to the original game," id creative director Tim Willits told me after I got hands on with Doom 3 BFG's 'Lost Mission' content. "Like the flashlight [which can be used in conjunction with your gun, unlike the original]. We made things a little bit brighter, we improved a lot of the character textures."

BFG features tweaks all around, from slightly increasing the player's speed, tweaking ammo and health, adding new soundscapes, an new auto-save and checkpoint features. "It plays better, it really does," Wittits promises.
