Playing NDCP2 for the first time, I'm on MAP22 I think. I'm using PrBoom+, sometimes switching to ZDoom to check if some of the things that don't work would work - they still don't :-P A buggy release it is indeed!
Until this playthrough I thought it was cool not to include SSG in maps from time to time, but here, in this release, I think the authors put it into extreme.
MAP18 is a nice, grey base, the kind of design I'm usually fond of. Shotgun and chaingun, all the time, and big piles of hell knights and barons. Doom_Dude, you must be enjoying all this stuff, but I don't. You put an SSG near the end (!), in a secret (!!), no signs of weapons no.5,6 and 7. This sucks.
MAP20 by PumpkinSmasher is much better, I even think one of the best so far. On my first try, however, I didn't find the secret berserk, nor the not-so-secret plasma (hidden in a similar way as the BFG in Circle of Death) and I was REALLY low on ammo with a shotgun and a chaingun. I think seven monsters are unreachable if anyone tries to Max it, but, as I said, I enjoyed the map.
