The map complex has a spot in one of the building’s where you can enter the wall and hide/ use it for protection.
As expected this can be a major game-play changer in game-type’s such as Odd-ball or Flood.
I am writing this not to bring use to this but to allow it to be fixed ASAP
A video showing the spot can be found at this link here -

bugs are expected for a few months tbf, i see how it could be a game changer :’) hopefully 343 doesnt go overboard when the patch them 
Yeah I realise they are expected xD
I did not expect something like this though 
That is why I thought I would try to get attention on it.
Was playing quite a bit of oddball last night, and after a few games I realized that nearly every game you had people trying to get the ball back into that spot.
It’s quite a find to whoever found it, but it seems like an easy fix.
