I Combined 25,000 Zombies Into THIS

Killing zombies and getting rich. Who doesn't love that? This mode is very fun to play and the fact it earns money on its own means I can leave it for months and be incredibly rich. I'm hoping I'll be top of the leaderboard soon. Game: Roblox - https://www.roblox.com/ Music provided by: (Epidemic Sound) http://www.epidemicsound.com/
