Base

Overview
The Base is where the player lives in, during a (presumed) zombie apocalypse. The player can upgrade their base with several different upgrades.

The player can upgrade their walls, eventually buying a new floor. This unlocks lights. This repeats for all floors. Items can be bought on each floor - weapons on all the floor except the top floor, which you buy armor from. You can also purchase Base Defenses. The Garage can also be purchased.
