How to install custom DLC: 1: Extract numbered folder (e.g. 123456) to game's DLC directory. 2. Open .ini file that came with game crack (e.g. steam_api.ini from reloaded, 3DMGAME.ini from 3DM). These can be used with legit Steam version, but you lose your save file. I recommend copying your game folder to another place on your hard drive before applying a crack to avoid issues with saves, steam overlay, and online play later on. 3. Look for DLC section in .ini file. Add a new line with the number name of the custom DLC you downloaded (e.g. last line is DLC007=358144, add a new line that says DLC008=123456). 4. Save .ini and enjoy.
