This has probably been suggested before, but I looked around and couldnt find anything on it, so if it has been mentioned, I apologize.
I’ve always thought the towns in Cata seemed really tiny, which is nice. But I think, for each world generated, one large city should be spawned. Of course, if this is ever implemented, it should be extremely far down the road, as I’m sure you guys (Devs, I mean) have more than enough on your plate right now.
Large cities would include mostly apartment and office towers, instead of houses. All stores would be four times larger, streets would be wider and more packed with cars, and cities would be extremely large. much larger than the current small cities we have now. Massive hordes of zombies would appear in cities, along with a much higher number of survivors. Areas of the city should be almost completely desolate, with only a few shambling zombies and packs of feral dogs, while other areas have massive crowds of zed-heads. Cities would be end-game areas, with loot to match. In addition to large gun stores and huge pawn shops, in some areas of the city, you’d find spray cans everywhere, trash, chain link fences, and, in garages and basements, caches of guns, ammo, and drugs left by gangs before Z-day. Police stations in cities would be renamed to Precincts, and they’d be the only place where you could find riot armor, which would protect against nearly everything except explosions, but would limit mobility, and bomb squad gear, which would protect against absolutely anything, but makes it almost completely impossible to move (Sort of like power armor, but lighter and doesnt require power). Survivors in cities are more likely to have guns and good gear, but in addition, they, for the most part, would shoot you on sight.
I also wish we had some sort of civilized areas. Places where humans were able to beat back the zeds before they started getting too powerful.
Bastions would be very small towns, or outlying areas like public works, hospitals, hotels or apartments, where humans managed to survive the first few days. They’d be characterized by having nearly all the windows and doors boarded up, several dead zombies (And maybe a few dead survivors for some loot) outside, and inside would be several (Take the number of zombies that should have spawned there with static spawn and convert them to NPCs?) survivors armed with whatever sort of weapons might be lying around that area. They wouldnt be willing to part with any items (So you cant farm them for loot) and if you attack one, they’d gang up on you, but they do give quests and rewards.
That’s all I can think of for now. I’ll edit this and update it when I think of more ideas. I realize none of this can, or will be implemented anytime soon, but hey, maybe you (The devs) might see something in here that gives you a little inspiration for something you could add soon.
