Well, i'm a mod developer. I like to modify the Doom videogame, using the classic GZDoom and Zandronum sourceports. I've been doing this for like, 12 years ;) I do also make some drawings and music but that's not related to this page.
I've managed to extract some CS:S and Portal 2 textures (512x512). Used them on Doom maps, to check how they look in-game.
