Yeah it looks ginormous.
Looks like a race track, remember that the players have to run with the cart.
Also some of those straight shots look very straight. Which means there are no turns/corners to hide from... Sniper fest.
Also looks like you did a copy/cntrl-L to mirror the entities, so they don't line up with the corners.
But back to your Q.
'What is this?'
I don't know, what is it?
