BFG - Big. Furious. Glorious.
This is an excellent upgrade to Doom 3, despite a few small flaws here and there (maybe annoying but nothing fatal). If you liked the game back in 2004, you will surely appreciate this opportunity to immerse yourself into this world once more, and play some new levels too!
Doom 3: BFG Edition is an updated (remastered) version of the original Doom 3 and its mission pack (Resurrection of Evil) with a few interesting extras
I noticed some changes to Resurrection of Evil's levels that I don't quite agree with - e.g; the removal of the enviro-suit sequence in the toxic sewer, or the dimensional flux effect in Delta Labs, and there is even an entire missing room in the final level.
