Another exploit is.. (don't look! Once you know you can't un-know!)
Start a fire, lure zombies near, and then throw any (single bullet of) ammo into the fire, where it'll explode with the force of a grenade.. The github crew is already aware of this and will eventually lodge it in reality (where a burning bullet harmlessly fires its casing in a random direction, while the heavier shot stays harmlessly in the fire.. For now, though, you can turn .22 rounds into high explosive, unless they've changed it recently..
But yeah, I love me some CataDDA :| I'm thinking, as the game progresses, we'll be able to totally remove zombies and insert any enemies we want.. In the end it'll be a
World Simulator, and modders will be able to make it into vastly different things..
Strip out all the buildings and start on a Caveman mod..
Strip out all the supernatural stuff and add in a realistic police system and create that "controversial" serial killer rogue (or flip it around and play as the cop/detective)
With enhanced illness transmission it could be a viral outbreak sim, modern-day vampire sim
Dino mod is already there for fun
Strip out all NPCs and zombies and just have fun in an empty Langoliers-style world (you can already do this)
With the current in-game digging mechanics it might end up possible to recreate SimAnt :O
You can already rid the world of living humans and zombies, and lower the city size down so that "civilization" is barely represented.. Add in the ability to play as non-human characters and the potential goes up by magnitudes.. Just surviving the cataclysm as a dog would be an amazing ride all by itself!
The possibilities are too much!! :| My favorite playthroughs so far have been when I (cheat)spawn myself a folding bicycle and a military rucksack and just
bike :> Never settle down or set up a base, only stop for sleep or gathering, and just cover ground on the ol' bicycle
