The latest codes in this guide are essential for keen mobile gamers after free rewards. Although new players will need to put in a lot of work first, the payoff is well worth it. 

As you fight against the undead in Joy Nice Games' roguelike shooter as a gun-toting potato, you'll find yourself in constant need of resources to upgrade your stats and loadout to clear each stage fighting off zombie hordes.

By redeeming codes for the game in this guide though, you'll be granted some instant amazing bonuses to upgrade your build and beat the later stages far quicker.

All codes

Each of the ten codes can be found in the table below, redeemable for essential rewards like Banknotes, Enhancement Blueprints, and Diamonds.

These codes can't be redeemed by new players instantly, though. You'll need to clear Chapter 5 (Molten Core) first for the option to become available.

However, after playing through the game personally, I was able to test each code and confirm they all work in giving out the above rewards with no issues. 

The Banknotes I found especially useful since you can use them instantly to buy stat upgrades in the Gene tab's upgrade tree for higher ATK, DEF, HP, and even to improve the effectiveness of Medical Supply items.
