Doom modders are bringing back the gameplay, maps and guns from the new Doom to the... original 1993 version. I love these sorts of demakes and in this case it's a demake of a reboot to get back to the roots of the original which is now becoming the reboot.... or something. Regardless these kinds of projects make the amazing aspects of the mod community shine.
I absolutely love that the Doom mod/wad community is still going. This just shows how timeless that game is. I need to fire it up again some time.
Oh that reminds me! I found one of the secrets in the new Doom which is one of the old maps. Once you discover a small area of it, you can apparently play it in another mode. I haven't tried it out yet, I just know I found one of the many secrets. :)
Yep, I believe you can unlock much of Doom and Doom 2 in the new game. I unlocked a Doom 2 level and was pretty stoked to try it.... until it kicked my ass. But it was still fun, I just don't remember it being that hard.
