Reason 2 Die is a popular ROBLOX game developed by PlaceRebuilder. It's a strategy game where survivors must fend off zombie hordes while accomplishing map goals. As they progressively unlock Weapons, Items, Armors and Ranks, the Zombies must attempt to prevent the survivors from doing so. Reason 2 Die is a free-to-play, although it contains additional in-game purchases that uses R$ (ROBLOX's currency) in order to obtain in-game bonuses such as Boosters, Secret Zombies and Cash!
