These are the first three maps of a megawad I work on, on and off, called "Hybrid Awakening." I wanted to release the first three maps to the public to see if I am going in the right direction so far. The story is pretty sparse. Your a creation that wakes up in an underground lab. You have an electronic eye-patch (hud-face lol) and a katana nearby. The UAC is defunct and some new organization called "Hybrid" is up to no good, cloning demons and such. Naturally you have to go into their tech-base called the "Kappa Tower" and kick their asses. Good luck.
Creators of the texture set for Greenwar 2, which I used a couple of patches from. Shadow Warrior, which I ripped the katana sprites from, and slightly edited. Requiem, which I got the status bar graphics from (cept' for the hud, which I made out of boredom.)
Map 1 and 3 is from scratch. You might be able to compare the center of map 2 to one of my older maps ;). Read the name and you might understand.
