Bleach: Hollow Flash

A event that when it starts and gathers all the players up to a map to fight in it begins to spawn mobs, hostile enemy mobs. What would be cool is if you and all the other player within the event had to fight off and survive against rows of mobs the mobs getting tougher each row till either all the players die or the row reaches it's max. What you'd need to do is defeat mobs and the more you kill the more cash you earn once the event is over if you survive that long. IF you don then you could get your cash reward divided by ten as you are eliminated
