I know it is going to be so amazing!!! OMG Doom 3 on PS3 with trophies good thing my birthday is very soon after it comes out im going to get it then. When i first got Doom 3 (Originally for the Xbox) i spent so many hours of my time just battling the demons and playing through the campaign god knows how many times XD haha Nothing can beat Doom, Doom is what gave birth to all FPSs we see today, the BFG edition will remind everybody of this truth.

Does anybody know how to edit the base campaign for mod uses? Just asking for some help because i am gathering all the maps and editing them using Dark Radiant but i want to know a way on how my changes would be saved for the mod that is in use, any help will do nicely :)

nbohr1more May 17 2012 replied:

Not sure what you are asking...

The maps are located in one of the base pk4 files and you could certainly modify them in the editor then dmap them and pack them into a new pk4 to be placed in a mod directory. Shipping that in a Mod would not be legal though. To my knowledge, there's no tool to "patch" maps to include new changes though I suppose you could save all your edits to a layer in DR then save the contents of that layer as a "prefab". It would still encumber the player to insert the prefab to patch the map though...

That doesn't sound like a bad idea thank you :) Dude you are very helpful with these things you know that, well i was thinking on contributing for the Allied Marine Squads mod and revamping the campaign to be much more hectic and with help by the many different teams of marines, almost creating an Alien VS Predator 2 feel to the game its just that i don't have any knowledge on how to do it. Dark Radiant is a very useful tool and i thank you for you and your team in creating it, i'll have to keep experimenting but if you do know anything please tell me, i will appreciate it very much :) Til next time see you round nbohr :D
