Roblox: Merge Tower Defense Codes

By newsgame

Merge Tower Defense is a Roblox game that manages to combine several genres at once, namely tower defense, tycoon, and even merge games. All of these game mechanics are wrapped up in a zombie apocalypse setting, where you will have to fight off ever-growing hordes of zombies day after day. To defend yourself successfully, you need to regularly upgrade your turrets and buy new ones. Fortunately, there is plenty of money in the game, as you earn it by destroying zombies and producing energy.

It may be difficult for beginners at first, as they will have little money, weak turrets, and a bunch of processes to keep track of. However, if you redeem the Merge Tower Defense codes from our guide, you will receive enough rewards to ensure rapid progress for long hours of gameplay.

Updated December 9, 2025, by Artur Novichenko: Merge Tower Defense adds several new options that you can use to collect a quick set of extra rewards. These recent additions sit alongside the existing selection, giving you plenty of chances to build up your resources as you play. Everything is simple to claim and helps you progress without changing your pace. It’s worth checking back again soon, as more updates may expand the list further.
