The talented Karthik Abhiram has announced on his homepage that he has returned to Doom mapping after a slumber of 3 years with a new project named "Stygian_Nebula". There is not much to see yet, however he has posted a story about the level with a rather classic storyline. Quote begin:
You would make your way into the teleport chamber, and then return to Origin base, where you could observe the destruction of the Stygian Nebula in safety. Unfortunately, things did not go as planned.
Ahh, nice! What would a Doom level be without such an intense and cliché driven storyline! So hurry over there and check out the rest!
