Description (written by the developer; not a statement by this register)
Undead Defense is a teamwork based zombie survival game where players are divided into two teams: humans and zombies. The goal is simple: humans must survive until the end of the 6 waves, while zombies try to infect all the humans. As a Human: 👤 Find a safe spot, build barricades, cooperate, fight off zombies, and upgrade As a Zombie: 🧟 Attack humans, coordinate with other zombies, and don’t give up: Even if you die, you’ll respawn and keep attacking until all humans are infected or until the wave has ended.

Monetization — game passes
Game passes for sale and their prices, measured from the Roblox passes API. Developer products bought inside the game aren’t publicly listable.
Badge funnel
How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
