Now I see this is not an April Fools' joke, I realise it is something worse. This gamemode is the end of EggWars.EggWars and BedWars on the same network?
Considering this was announced 1 week before April 1st, it's most likely an April Fools' joke.
In the following months, EggWars will likely join BlockWars 5v5 in the shadow realm as CubeCraft pushes Bedwars (it's funny because EggWars directly inspired Hypixel Bedwars). Because why would they keep both, especially when they are actively developing Bedwars? This is also happening after Hive renamed Treasure Wars to Bedwars.
