Martin Perez has let me know about a new Doom 2 TC in the works entitled Teenage Mutant Ninja Turtles: Hostile Takeover. The official site is now up and open to the public. And now for a quote because I am lazy:
This project needs all the help it can get, so if there are some fellow Doom-ers that will help me with the project ( Mac or PC ) I would greatly appreciate it! This project is currently being made on a Mac and will likely have a demo of some sort in the next month.
