I'd like to take this opportunity to give a great big hug to whatever glorious fellow implemented caltrops.
You've tripled my survival time. I'm up to three days now.
Fellow, lady, whatever.
You're very welcome!
That also reminds me that I need to start repopulating my idea list again. If any of y'all have suggestions feel free to toss them out here and I'll consider adding them to the TO DO list.
Most of these are things I've been thinking about trying to add, once I finish my current project. My C++ is rusty though, and I likely wouldn't be much more than a drive by developer at best, so if you or any of the more permanent contributors want to implement them you're welcome to.
-Prisons should be populated with "Prisoner zombies" instead of bog standard zombies. This would let them have a unique loot table, clearing up the "prisoners carrying hammers and wearing bondage gear" weirdness. Makes them funny, but a little surreal.
-Most vegetables are downright impossible to find after rot sets in. Some, however, wouldn't be too hard to find in the wild once society collapses. For example, tomato seeds are one of the few seeds that can survive the human digestive tract (at least, of the foods we regularly eat). With the filters turned off, the sewage systems would become overgrown fairly quickly. I'm imagining the sewage plants becoming overgrown with mutant plants, killer tomatoes, and zombies covered in waste. Turns them from a boring location to a veritable goldmine of post-civilization food - if you can stand the stench (and disease).
-There aren't nearly enough drink cocktails in the game. Only two don't involve vodka (Rum & Coke, Irish Coffee). Makes being an alcoholic kind of boring, and can get frustrating when all the cider/OJ is rotted and you can't mix any cocktails. A full on mixology addition would be interesting.
-On the subject of alcohol, the Still is pretty much useless. You can use it to create one crappy mutagen, and two horrifically bad drinks that are less useful than their components.
-Given the recent excitement over 3D printing irl, it would be pretty cool to have 3D printers spawn in the Labs. Put recipes on the USB drives to give them some actual use, maybe have useful recipes show up on computers in various houses and/or military bunkers that can be loaded.
-Rolling suitcases, folding laundry carts, and other containers that can be dragged like shopping carts but are light enough to be packed up and carried or stored in a car like the folding bicycle.
-Plenty of zombie options still remain. Zombie Hipsters, Geriatric Zombies, Zombie Lawyers, Zombie Deer, Zombie Moose, Celebrity Zombies, Zombie Security Guards... the list goes on and on. Most of these would just be for the satirical effect, but the recent addition of uncommon-common zombies has made the apocalypse much more colorful.
-On a related note, there are plenty of opportunities for special zombies as well. Splitter zombies (a la Dead Space). Regenerator Zombies that get back up two or three rounds after being killed and come back with full health (or better, come back stronger). Cannibal Zombies that eat their fallen comrades and grow stronger. Gassy Zombies that explode when they catch fire (or are hit with a flaming arrow, incendiary bullet, flaming sword, etc). Vampiric Zombies that try to grab and bite you to regen health. Venomous Zombies who's bites carry poison instead of disease. Mutant Zombies that have scorpion tails, horns, or fangs. Bionic zombies that are part machine. "Possum" Zombies that look like normal human corpses until you get next to them and they get up to attack. Cryogenic zombies that take little to no damage unless you hit them hard enough to shatter them. Hive zombies that spawn goo or some other type of monster. Diseased zombies who's bites are even more likely to cause infection. Burrowing zombies that hide under mounds of dirt. The list goes on.
