Since I watched "Die Hard" yesterday, I thought I give this mod a replay after eight years. It's actually even more fun with fresh memories about the movie in your head, even though the limitations imposed by the setting of the episode remain the same as before.
I challenged myself by playing this in Rednukem, which required a few modifications on my side (i.e. mostly getting rid of the level randomizer code and any other EDuke32-specific stuff Rednukem wouldn't understand). To my surprise, the maps themselves remained quite playable, with some visual glitches here and there (mostly moving sprites like helicopters or scaffolds doing jerky movements) plus a single real showstopper in DH5 "Abstratech" where the switches to rotate the command center would move around like crazy (instead of moving with the sector) after rotating the structure once. DNCLIP was required here. I am not sure if this is an EDuke32-specific feature or a Rednukem bug, but
I reported it on Github.
Besides that, 16 out of 17 maps could be completed without cheating (Rednukem apparently has no issues with episodes exceeding vanilla limits) and it was quite entertaining. The only map I didn't like so much was DH12 "Poormann's Library" due to its constant dimension hopping which felt kinda glitchy. (Reaching the secret level was ofc a no-brainer due to my knowledge from the movie I had just watched the other day.) The general concept of having a bunch of shorter maps which can be completed in 10-15mins each max is still a concept that works well for me.
