Haidrgna, thanks for the response and this awesome variation of the game.
I restarted a new world, and everything was working fine (felt a bit more confident thinking I knew what I was doing). Got a nice area, built a nice 7x7 pole base, and was nicely stocked with weapons (best lot of the 3 tries so far). Night one was as to be expected, everything held and I could do mostly melee to save ammo. Day 2 was spent upgrading, getting some workstations upstairs (workbench, forge and chem station) to start production on ammo. The stash had a lot of food (but almost no ammo... no biggie I thought). Did some exploring, got the air drop, and waited for night 2. It was a nice fight. Had some exploding Big Mommas, and a few waves of Zs... was a good test for day 2 with only poles and no other defenses. Day 3 was mostly a waste as I was searching for a water source to fill my jars so I could make more glue (needed in some recipes). Did not fine any (GNASpose2) in my seed. No biggie, if I could just find some tires, I'd have a minibike so I could drive around. VERY FEW tires around, went 0-for-2. Made about 20 explosive x-bow bolts and got ready for night 3.
HOLY BALLS!!!! I ran into what Dreamdancer did. When they started coming, I was looking west and saw about 10-12 banging on that wall. Cool, no prob, gonna destroy them with my explosive bolts. Bam bam... awesome. Look to the North... there are 10-12 banging on that wall. Look to the South, about 10-12 banging on that wall. Afraid to look behind me, as the noise there suggested the same. Uh oh. At 23:00, I'm outta bolts, and the poles are about to crumble. Climb upstairs and kill over 50 Zs (because I had to re-read the quest when I got up there and once again before the whole thing collapsed).
So, yeah, that happened!

Was momentarily frustrated at the insane exponential increase in horde strength... but then realized... this was the most fun I've had in a while. Kudos to you.
Gonna dust off my pride, put it back on the shelf, dream a little bit about what I need to do differently, and I'm gonna conquer Night 3 tomorrow. Probably not, but 'eff it, I'm gonna try!!!
Thanks Haidrgna, really, thanks! Keep up the good work, looking forward to seeing this thing progress.

Hmm. Playing horde mode, I think the hordes might need a touch of rebalancing. Night 3 I got a horde that felt like a night 70. At least. 2 cops, multiple Wights, tons of spiders and utility guys(who do high block damage), birds, and a truly absurd number of total zombies. With 11 wide walls, 2 full walls were stacked to the brim with zombies, with more behind unable to reach the front. And for every zombie I killed, 2 more seemed to take their place. And way, way past the blood moon limit. This was the kind of horde I usually have steel walls, fans, and turrets before facing. My concrete toothy and barb wire was annihilated. It was a rout.
Really, really love the mod, it's the most fun I've had on the game for a while. But it feels a little disheartening to so quickly run into something that seems quite literally impossible so early on.
Me too, just ran in to the insane Night 3 attack. Was not expecting THAT!!! Holy Balls!
I've never played Multiplayer in 7d2d, but I think for this mod, this might be a good idea (if the lag/frames don't make it unplayable with so many Zs at once--maybe the lack of trees, buildings, etc. will help balance the load).
