I like making mods and even total conversion Doom mods! I play Doom since I was 3 or 4 years old so it was a matter of time when I will start to making mods. I really love old fps games! I'm also a huge fan of post-apocalyptic games like Fallout series, Metro series, Stalker games and books, Ashes a total conversion Doom series!
