Prison Break can be found HERE in the online map browser so add it to your favourites and give it a go.
The map starts off at a good pace then it all goes relentless as they keep coming at you, moving forward I thought blowing up the truck would be close to the end with a couple of sniper towers and a heavy guy but how wrong I was.
In the end I had to do a runner and leg it to the extraction point, very difficult this map because a lot of the time you are in confined spaces - I think in COOP it will be a right blast and a lot of fun.
Nicely made - DAVIDLEONARD also made The Walking Dead and Northern Lights which are also good maps to check out.
