Here's the news that I saw at doom3.ru. Thought this might interest some modders.
Tech guru c4tnt presents new project extending Doom3's functionality. The author says:
Doom3 DLL Mod - DLR
The mod doesn't change the gameplay and aimed mostly to those who like to create their own maps for d3. Adds support of:
*Adjustable difficulty levels
*"Use" key - impulse 40
*Lasers like in q2
*Glass grates, you can shoot through them
*Fixes n bugs
*Some debugging instrument
%Ability to see your body
%Hubs (connected levels like in Hexen)
*Many weapon slots
*Dual weapon slots, like in RoE
and many more.
Now you can download the source codes here:http://c4tnt.ucoz.ru/x/DLR_SourceBackup_12_dec_2011.ZIP
A while later there will be compiled dll and documentation. I will continue to support the project, you can leave feature requests, but requested features must not break the standard gameplay.
