Yeah but hex turn based was already done in Dead State, I would not steal that from them, if you want inspiration tho, check out there sound system for attracting zombies. Every action had a decibel rating and radius that zombies would hear it from. If you broke a certain level then zombies would spawn at the edge of the map and move to the sound.
So breaking down a door with a sledge hammer makes a lot of noise, with a crow bar a little less, picking the lock makes even less noise. So breaking down a door then shooting a zombie with a shotgun would have the zombies coming form the edge of the maps and moving towards the sound, spawning more as noise increased.
Back a long time ago the sound for this game was awesome. I know it was broken but hearing a long distance allowed the game to have a much creepier vibe when you could hear the footsteps getting nearer or farther away based on how loud they were. When a random horde would come shuffling by, or a pack of dogs was running near. Or the sound of the bear huffing in the distance. Now the sound seems dull, to low, etc. I really hope one day you guys revisit the sounds and the systems related to sound so the game regains the creepy scary feeling at night when the zombies are moving around.
I hate that I can break down a door with an axe and not a single zombie hears it, even if they are just inside the door. I only get detected if they are facing me and there is a bright light source. Chopping down trees or mining in the open should make lots of noise, it used to, now it doesn't. How does crouching lower the amount of noise? I find this laughable. If you lowered the amount of damage your weapon did, then lowering the noise would make sense.
