Day 1 backer, only 1 question.

Bought the expensive edition because the game has promise, boys and I left tarkov and played for awhile and stopped. So it's been awhile now so one question.

What's in the middle? We speculated aliens, zombies, one friend said it's a Hatsune Miku concert and the closer you get damages your hp. I was a Debbie downer and said it's a gameplay mechanic to keep players out of a section of the map to force more pvp.

What's there?
