Grave Danger

Grave Danger is one of the 17 hidden Mini-games, which can only be accessed in the Limbo Page by using a Cheat Engine.

In this game, graves appear any time in the game. During the first flag, some zombies will come out from some graves.

Strategies
This level will be difficult to beat if the player does not purchase the Imitater. The graves would keep respawning and the player must use Grave Busters more often. The player can use the Imitater version if he or she wants. The player should remember to watch his or her sun, but it may be easier if he or she were using Sunflowers. The player can use Twin Sunflowers, but he or she does have to upgrade them. If the player survives the two flags with many graves, it will be difficult if he or she has not removed them yet. The player may use a Doom-shroom, if there are too many zombies. The player may want to do the Recharge Hack in Cheat Engine.
