Hey SaltMaster,
Getting the orbs back to the monolith is the ending right now, all you have to do is return to the base to finish. the car saves at whatever position it was on save. I added that the zombies themselves drop bullets which has really unbalanced some dungeon rooms. I'm working on that, there are limits to how much resources and bullets you can hold now, based on the house level. Stone will be the next upgrade level land world material, then Bricks, then Steel. I also want to add a whole line of build items per house upgrade.
Thanks for the feedback, support and suggestions, lots more comming very soon, Stay Tuned!
