Beat the horde on Pavillion

A random group and I beat all 50 horde waves on pavillion last night.  We had to restart a lot of times, but eventually beat all 50 waves.  We had to use two strategies to make it through all 50 waves.

Our main strategy was to stay in the hallway where the ammo spawns (in front of the room where the shield spawns).  Every wave we grabbed the shield that spawned and placed it in the doorway at the end of the hallway.  At the end of every wave 2 or 3 players would reset the shields.  One or two players would run for grenades in the halls on the side of the map.  The last player would run for the mulcher in the gazebo.  We would all take turns grabbing the ammo box as soon as it spawned to make sure we all had max ammo at all times.

We shot over the shields on both ends of the hall to keep the horde back.  When the horde got past the shields we would all focus on the side that was breached, eventually falling back in the shield room and defending the small hallway to that room.

We were all beaten at wave 40 and restarted at that level.  We did not have any shields.  We kept trying to defend the shield room, but the bloodmounts were too fast and that room was too small to beat wave 40.  Finally we tried a different strategy which was to go to the lowest part of the map (down the stairs on either side of the gazebo).  From there we spread out so it was harder for the bloodmounts to take us all out.  There is a small corridor between the two sides on the lower part of the map where the mortar spawns. We made sure to grab the mortar whenever it was available and kept firing rounds at the stairs to the lower areas (whether we saw an enemy or not). If a bloodmount did make it to the lower area, we would run through the corridor to the other side and fire back through the corridor at the bloodmounts who had a harder time making it through the narrow corridor.

We had to try that strategy a few times before beating wave 40. Once we beat that wave, we went back to our original strategy of defending the hall and we were able to do that without much trouble once we have a few waves to get our shield defenses built back up.
