In order to make Ernie a game with a ton of replay value we've added a combo system. Based on how much you can kill in a row the player will earn orbs. The orbs can be used as currency for making back alley deals to modify your weapons and armor.
We have 10+ upgrades, new weapons and armor to purchase and level up. The better you do at eliminating the undead the easier it will be to fight. I'll post all of the upgrade types soon as well as the weapons.
