All the players begin with three lives each, which are taken out by a melee or ranged hit.
When a player loses all of his lives, he is destroyed but not defeated, he merely enters a "cloud" state while his body is scattered around the entire planet.

In the cloud state the player must gather the pieces of his body back. Every time the player returns, he is granted an additional life, but i when you die again, you have to get an additional body piece to return, keeping it balanced like this: The more you die, the harder it is for you to return, but when you return, you are stronger, as in the concept of the Ouroboros, where you are in a cycle of eternal return, and keep coming back to yourself evolved and stronger.

Call your friends and have fun!
