Doom has always been big when it comes to modding, so it should come as no surprise that the new game isn't any exception. A group of modders (DBThanatos, Major Cooke, and Michaelis) have taken parts from the newly released Doom and recreated them with old school graphics. The new weapons are here, the modifications as well, and you can even do the glory kills. The mod is called Doom For Doom (D4D) and you can check it out on YouTube.
Perhaps it's time to boot up and play some classic Doom again, no...?
Thanks, Kotaku.
