I was checking the beta and it seems most of its content was actually dated about early february 1998, between then and May, they cranked to finish the game.
In some ways I wish they finished the game as meant than the rework, woulda been interesting, still leaves a lot of holes in the unreal storyline.
I found the GWPress levels in my Unreal220 folder, I have the game installed in its many versions all over the place, so its saved, I wasn,t aware I still had them until I went into the wayback machine to try to identify which maps it was. There they were. Other post release maps I also had from special versions and so on. They will be included also.
Not the creative demo maps tho.
