Half Life 2 Meets Doom In This Spectacular Garry’s Mod Add-On

Doom-Half-Life2
Now this is simply amazing. YouTube’s GhorsHammer is creating an incredible add-on for Garry’s Mod called gmDoom. According to its description, gmDoom is a partial source port of Doom integrated into Garry’s Mod 13. Assets are loaded from an IWAD, and no binary modules are required. The good news is that this add-on will be available through the Steam Workshop once bug testing is complete, which – according to the modder – should be in only a few days. You can view a video demonstration below, so make sure to give it a go!
