I'm sure this'll be fixed in an early patch.

On Complex, there’s a building in which people can jump into a spot right above a door (it’s the building in the far corner next to where the red team flag is I believe). Once above that door you can travel in the walls of the building, accidentally fall through the floor to suicide, or even die and it will say someone else killed or even assassinated you. Since my group saw someone do this in Flood to hide, I’m sure this is something many people know about now. Hopefully it’s fixed in a patch because exploiting this map error in games like Oddball make it impossible to overcome.

Yeah, people do that all the time in Flood and completely ruin the game. Here’s hoping they’ll fix it soon.

The Complex glitch is the single most common thread topic I see on here
