Played Survival for the first time last night. We started in the hospital level, I forget what it was called, but the one where you are waiting for the elevator. We hid in one of the patient rooms and figured we would be safe shooting at the doorway.
As soon as it started, the wall behind us burst and a horde flooded us. then another horde started to come in from he ceiling on top of us. We lasted a 1:15. It sucked. We had no idea what was gonna happen once we called the elevator.
After trying a bunch of levels, we managed to Bronze a few, but at the end of the night our longest time was only 5:23 I think.
We tried hiding in the brick garage in Lighthouse, thinking "they can't break through brick, we'll be safe here. Once again, we were wrong. Lighthouse destroyed us the three times we tried it.
