Mapping goes, working on the scavenge and versus counter-parts currently, level4 after that.
Waiting on Nitro to help me with the nav on level3 in the elevator shaft, so I'll do the scavenge while I wait.
The only difference in the versus versions is the fact that I am readding explosive barrels to level1s first crescendo and that I have to redo the item placement.
Level1 has the 3rd crescendos gate open after 45 seconds in versus as well. So there are alternate paths in level1 for versus that I didn't include with co-op since only in versus are we afraid of hunters grabbing us on tall ladders.
The other difference with level1 is the armory is gone and the plane crescendo always occurs. So that's 3 events in every map except levels 3 and 4.
Level2 has 25% health on each pillar in event 1 and no tank spawn after crescendo 3 is completed.
Another difference is that level3 might have every path open so players can choose which way they go at any time.

There are more differences but I don't care to list them.
I shortened level3s ruin path height in the stairwell to save on brushsides and vertexes, hopefully no one minds that.
In retrospect, the elevator event replaces the stairwell height in a way, high pounce hell.

So the first 5 (or 4, haven't decided yet) Scavenge maps and the first 3 coop/versus maps in the next release. After that we will do the last 2 survival maps, last scavenge map and the last level and its' versus counter-part.

I thought about a joke ending and then I changed my mind.
I don't want to make a fifth map, and it wasn't my idea in the first place.
Frankly I'd rather the survivors fail than have a happy or funny ending.
