Overall this is a decent map. Could have used a few more enemies. I did discover an issue though. When using the switches at the beginning you can accidentally screw up the buttons but double hitting the activation switch. I think is that the door begins to open slowly and when I double hit it, the door stayed open. Then I hit it a third time to activate the door and it closed. I got stuck for 20 minutes and had to use one of the let's plays to figure out what was going on.

Very nice map and single player was very fun
