That's right! T.U.C.Q. Release 6 is now available!http://www.doomlegends.com/chexquest/frames.html
Now all that stuff you saw in all of the progress reports can be seen by you in person, and now that T.U.C.Q. is an IWAD, you won't have to hunt down a copy of DooM or DooM II anymore.
TUCQR5 is for GZDooM. It will work in ZDooM and Zandronum, albeit less well.
Well, what are you waiting for?
