The first map was mostly intact when I found the files so it was just a matter of making sure the portals were ok, double checking the sound files were working and playtesting it to find bugs.
The second map was less finished but after a few days of testing, modifying and testing again I can safely say it's now playable but my playtesters haven't done their tests yet so i'm unsure of any bugs. I knew people would find a way out of the map no matter what I did so instead, having been a DOOM fan for most of my life I left little secrets around the map, some text here if you get out of bounds, a secret rocket launcher if you can find a way on the roof, and some not so nice secrets such as accidentally making high level aliens spawn if you mess around too much.
It was fun though! And now it leads into level 3 quite nicely. However level 3 is where things now get more tricky... The map is barely functional at all, it's from a very early build of it so there's no textures, no enemies, and the sequence I made for the tram doesn't function. So I feel like this is going to take up the next month or 2 just getting level 3 working. In the mean time I'll have some playtesters check out the first 2 levels and then I'll upload those as a demo while I'm working on Level 3.
