Aw, chill dude! This was not meant to be an easy map at all. In fact, from what I know, there was a playtester or two who completed this in one go with their FDAs albeit not their very first attempt (for some bloody reason I cannot remember, it must've been dew, and this was with the initial design which was somewhat more unfair actually). I was a tad worried whether the traps were too dickish but the responses were generally good so I stuck with it. The map is fairly short so replaying after stupid deaths is less frustrating than it would be if it was a longer map; I kept this in mind too. You better buckle up anyway because Resurgence Map26-30 isn't going to get any easier! :-P
Ok, I give up on map 29. This is just stupid.
Arch Vile that you can't take cover from guarded by imps that you can't shoot because of the angle. Yeah, that's a good idea. Follow it up with another "hope the monsters flinch, because there's not enough room to dodge in this hallway" battle.
Next up, a fight that's reliant on infighting where, because of the way the Cyberdemons are initially placed, if the RNG doesn't favor the player, the infighting won't happen and the fight won't be winnable! Oh, and then there's crushers on the outside so that even once the Barons are killed, surviving the two remaining Cyberdemons is entirely a RNG-fest based on how they move! This seems like it's supposed to be a tribute to Nukefall, without realizing that Nukefall was playable only because the entire opening setup ended with two properly-placed BFG shots, thus making it take about 30 seconds from map start -> end of somewhat luck-driven encounter.
Then, two more Arch-Viles that, if they run out their little alcove before deciding to slow-fire you, you've got no cover from. Hooray for more RNG!
Then comes the PEs' acting as the traditional SOD-style "This will kill you the first time, and won't do anything once you've seen it once" trap.
Then you slog through a few entirely uneventful fights (including shooting through keybars that a pair of Mancubi can't shoot back through), grab the blue key, and it's time to fight two Cyberdemons on the worst bumpyfloor ever that makes it nearly impossible to actually dodge projectiles. Then you get another Cyb- this one can't actually hurt you because of the way his platform is shaped- and then a Mastermind, and that's as far as any of my runs have gone, and I have no idea what comes next because this level is stupid and I don't care anymore.
As for Map30... I'm too traumatised to even remember my playthrough! *shivers*
