The Game Stops Concert For Fallen Fan

It all went down on March 18th -- The Game was in the middle of his performance at The Observatory in Santa Ana, CA ... when a concertgoer passed out in the crowd.

Game immediately jumped into action -- slamming the brakes on the show to make sure the kid was okay.

The footage is pretty intense -- the kid comes to for a quick moment ... asking for water ... then falls limp AGAIN, passing out cold for the second time.
