Highest level on Survivor Co-op?

Me and my mates managed to get to round 100. Anyone got higher?

On what map?

I'm sat here writing this whilst on level 320 on Biohazard..
Big combo (hard) Survivor Co-op mode

The creeps have not been getting any further for about 100 rounds now, was wondering, is it possible to get a perfect set-up in which you can never ever lose? If so, I think we may have just created it xD

I'll post the link of battle report IF we ever lose lmao

it was the same in speed coop. If you have placed rockets nearlly everywhere no creeps came through. That was also one of the reason why the new set up came. Most of the survivor coop map maps are that long that if you have a really good set up no creeps will get throw
