A recreation of the much favoured Doom 2 map 07, Dead Simple. If you enjoyed playing the original, you will love this. Unlike some remakes of this map, the layout is exactly the same as the Doom 2 level, even with the Redeemer replacing the BFG. If the redeemer is a bit excessive for you (the BFG was pretty excessive in Doom 2), just turn it off with the No Redeemer mutator.
Refer to the page on Unreal Tournament levels for more details on how to install and use the level.
