Flood was a minigame added in ALPHA stage. This minigame had two versions made for it. The first version of the map was made in the early ALPHA stage, being quickly removed a couple of updates later. The minigame required players to solve a simple puzzle, to then later escape. The newer version of the minigame was never scripted and was scrapped.
Removal Reason Edit
The old version of this minigame was removed because of how confusing and cramped the minigame was. The map was very small, and felt cramped for most players. The minigame was also confusing and had no real indicator for where you were supposed to go. The new version of the minigame was removed because the minigame did not feel playable outside of Solo Mode.
