@xKrazyx You've done an absolute amazing job so far already!
You've got me intrigued!
A project like this can take ages, so dont mind taking your time!
I do wonder one thing; What will be the goal? Are there still monsters available? Or is this more of a survival game between zombies/players? ( That would be sick aswell! )
Ohh, I also had some ideas:
Is there a way to defend your base? E.g. hidden traps or Turrets ( o_0 That would be sick! ) Perhaps a way to upgrade your foundation/wall with stone or perhaps some other sort of material?
Some sort of 'Artifact' made out of dead zombies, providing you some buffs, or the raiders some sort of handicap?
There are so many ideas going through my mind. You have a project here where the possibilities are pretty much endless.
I wish you the best of luck!!!
