So people would get in spots where zombies couldn't kill them & leave their PS3 running, eventually zombies die on their own to prevent a zombie from ruining a game by being trapped outside & unkillable. after leaving your PS3 on for days & risking YLOD, you get round 2147.
That's not the only reason for 2,147,---,---.

The number 2,147,483,647 is also the maximum value for a 32-bit signed integer in computing. It is therefore the maximum value for variables declared as int in many programming languages running on popular CPUs, and the maximum possible score (or amount of money) for many video games. The appearance of the number often reflects an error, overflow condition, or missing value.[7]
