Merge Tower Defense is here to help you fend off a relentless zombie horde. The formula is simple: merge those weapons to pack a bigger punch. The bigger the boom, the better your chances of protecting your territory. Those undead won’t know what hit them!
Want to amp up your defenses? You can snag free Diamonds by redeeming Merge Tower Defense codes and cracking open crates for exclusive turrets. This gear will transform you into an unstoppable zombie-slaying machine! But be warned—battling the undead is one thing; battling evil toilets is a whole different beast. Quickly merge camera people with Merge Titan Army codes to assemble the ultimate force to tackle those pesky toilets!
