You heard that right. Game HacKeR sent me an e-mail saying John Romero released a new Doom maps to replace E1M8. I haven't gotten to play through yet (because I want to play through the whole campaign vs the single map) but I got a couple screenshots for you.
You can download it from the DoomReborn site.
If you have a map release you'd like to see posted here, use the "send in news" link on the right.
