Zombies Immortui

A platform shooter with zombies, weapon upgrades, and barricades. Click on the green supply crate to upgrade your gun. If you don't have enough for the next upgrade it will upgrade your current weapon. Your damage and money gain will increase and your weapon along with your weapon changing colours. You can shoot through the hollow floors.  A health pack will come down from the sky every so often. Health packs will only heal if your health is below 50%. I know barriers don't last that long but I feel the game would be too easy if they lasted any longer. Camping in the corner is safer but you will get less in game money.
