In PlayerUnknown's Battleground, there were rumors where one who held a Frag Grenade could die together with an enemy and would both "share the chicken dinner."
In actuality, mutual destruction was theoretically possible, but those two players might not necessarily share the chicken dinner.
PlayerUnknown's Battleground had countless processors to compute data, such that it could accurately process even milliseconds and nanoseconds. This indicated that one of the players' health would become zero first at one specific point of time.
By the looks of it, the player with the chicken dinner was also killed by the explosion, but the data did not stop computing in reality which was also why that player was not eliminated. Consequently, there was no "shared chicken dinner."
In other words, whoever died first was the deciding factor of who would get the chicken dinner in the end.
As for who would die first, it depended on who was closer to the grenade.
