Installation: Extract the DOOM3toDOOM2_v1.0.zip into the doom 3 directory (not the base folder!). Run Doom 3, select the Mod "Doom3 to Doom2 v1.0", start a new game and select a difficulty. Note: Resurrection of Evil comes with patch 1.2, but this mod needs the newest patch 1.3 of DOOM3!
BEST MOD EVAH!!
I agree with the comment above me
I like this mod. By adding just a little bit of shadows, it will be perfected!
