Zombie Merge Tycoon

Zombie Merge Tycoon is a hybrid merge-tycoon game on Roblox developed by verified group OMG - One More Games, the same studio behind Zombie Hunters. Launched in October 2022 and still actively updated, it has grown to over 71.8 million visits with 136K favorites and a 94.2% approval rating - making it one of the more successful merge games on the platform. Up to 10 players share each intimate server, keeping the pace focused.

The core loop combines two familiar Roblox genres into one. Players buy low-tier zombies from an in-game shop, place them on a grid, and merge two identical zombies to create a stronger one. Higher-tier zombies generate more income per second, funding more purchases and driving the merge chain upward. The twist is that this idle income isn't safe: bosses appear periodically that must be defeated using your zombie army before they disrupt your tycoon operation:

• 💰 Merge mechanic - combine two identical zombie tiers into one stronger zombie
• 💼 Zombie tiers - higher-tier merged zombies generate more income per second
• 💎 Boss fights - periodic boss encounters requiring a strong zombie army to defeat
• 🏠 Grid layout - the play area where zombies are placed and merged
• 💰 Double Money gamepass - doubles tycoon income (350R$)
• 💼 Auto Collect gamepass - automates resource collection for idle play (150R$)

The economy runs on two resources tied to progression: standard income from zombie tiers funds more purchases, while the Sample resource (doubled by a gamepass) represents a secondary progression material. Nineteen achievement badges tied to merging milestones and boss victories give the grind a clear set of targets to work toward.

Mobile support was in development as of early 2026, with the developer preparing to bring the merge loop to touchscreen players. The game also shares developer DNA with Zombie Hunters, so players who enjoy OMG's style across both titles will recognize the production quality.
