You can now play World Zombination on Android. This is a tower defense game where you can choose to either help the surviving humans or the zombies!
“Gamers playing as the zombies choose waves of enemies that rush survivors in massive swarms. Controlling humans requires placing units at key strategic positions, which they defend with their lives.
More than 100 units, each with their own special behaviors and skills, engage in this MMO tower defense action. Players employ strategic thinking when selecting which units will be taken into battle, which will be upgraded and what direction on the skill tree a unit will evolve.
Gamers battle with and against thousands of other players in real-time for control of the world. Guilds can be formed to combat opposing factions in epic battles. The victors are awarded powerful new guild perks, with the best performing players reaping the most rewards.”
I have tried the game and it is not bad. It is your standard tower defense game. The different types of units and deciding which side to play does add some nice variety to the game. For the the game looks best on a larger screen. If you enjoy tower defense, give it a try on Android or iOS.
