Zombie lab [Equal Avatar Scale]

Zombie lab [Equal Avatar Scale] is a viral asymmetric survival game on Roblox created by solo developer sulkang, with over 209 million visits and 236K favorites since its April 2021 launch. Two factions face off in 20-player servers: Humans must craft a Cure or eliminate the zombie threat, while Zombies must break through the Isolation door and convert the entire human team. The game recently crossed 100 million visits, a milestone the developer celebrated in the game description.

The "Equal Avatar Scale" in the title is the game's signature differentiator. All players are forced to the same avatar height, removing any advantage or disadvantage from custom avatar sizes - a fair-play measure that matters in a game where physical space and movement are survival tools. The two factions play very differently once the round begins:

• ⚔️ Isolation door - the starting barrier that Zombies must break through to begin infecting Humans
• 💎 Cure - craftable item that converts Zombies back to Humans rather than killing them
• 🎭 Equal Avatar Scale - all players normalized to the same size, removing avatar height advantages
• 🏆 Virus machine - gamepass (449R$) that enhances zombie spreading capability
• 💼 Cure machine - gamepass (160R$) that accelerates the cure-crafting process

Humans face a choice: take the time to craft the Cure and save their infected teammates, or simply kill zombies on sight for a faster but less cooperative approach. Zombies who choose not to attack can even take the "peaceful zombie" route, though most rounds involve active infection chains. Any Human who dies while infected automatically joins the Zombie team, turning the game's momentum as the infection spreads.

The 65.2% approval rating reflects the polarizing nature of asymmetric games - some sessions tip heavily in one faction's favor - but the massive visit and favorite count confirms that the core loop keeps players coming back. The developer maintains a separate test server for development previews.
