Merge Rush Z

Merge Rush Z is a simple idle defense shooter game. Your character automatically attacks the advancing zombie hordes, collecting money for each kill.

In 'idle mode' your character will safely hold position, killing zombies even when offline. In 'stage mode' the risk is higher, but beating a stage will advance your position even in idle mode. In 'stage mode' the fire button can be held down to attack faster, though this will drain the power meter. A limited amount of airstrikes, medkits, boost drinks and electric shields can also be used for some extra help.

Collected money is used to buy guns, while two guns of the same kind can be "merged" together, upgrading them to one gun of the next tier.

Over the course of the campaign you will also come across a few other survivors, who will join your team and boost it with passive abilities such as healing, defense or extra attacks.
