I wanted to add a video where I went through this map, but I have an error with information about the video. I can not add a video - when I try to get an error that the video is invalid.

I just tried to get the game to crash by the ambulance. No dice. I tried everything: fought a tank, bashed a ton of zombie heads with the driver, ran around and hopped up and down on everything in sight. No crash. Sorry, guys, I don't feel your pain. On another note, once me and the bots made it to the second level of the parking garage I saw that I could get up on a railing wall that overlooked the fence area that gets blasted by the cannon. Well, let's explore! I managed to hop all the way over on top of the turned-over semi, hopped down and...and...the way back over to the cannon was blocked by an invisible wall. Darn. Am I now stuck here? No! Incredibly I was able to hop up onto the semi's tires and onto a nearby tall lamp and onto the semi and...and...there was a ramp over the coiled barb wire back down into the ambulance area, like the author figured somebody was going to be dumb enough to try hopping down on to the semi. Wish I could have gone over and fired the cannon, though. Next playthrough maybe I'll fire the cannon on level two, get the bots over there then jump onto the semi and transport myself back to the first map. Think that'll work?

I just replayed my version again and took notes. You're right, only one ambulance and that's on the first chapter. Again, me and the bots cruised through with no crashing. On the second chapter, the area below the cannon, well, we hesitated a bit instead of running over to the area that the cannon blasted. I went back up the ladders to get a health kit after an unseen witch got me. Anyway, the exploding fence over there is a timed event and if we're just not near it we don't get incapped. And again you're right, no ambulance over by the blasted fence. I saw some scaffolding to the right once we got through the blasted fence but we don't use it in my version. It's a tough finale but with plenty of escape routes to attempt to avoid the tanks. We all get beat up pretty bad but on Easy, in the words of Nick "at least I made it".

Herby/Huck, as I suspected your new map 2 path means that I don't have to activate the cannon at all, since the path is already laid out for me. I can have a leisurely stroll to the safe room and save the bots health kits for the finale where they actually need it. :P . You can still go the other way instead of the walkway to the scaffolding though, and can go inside the map 1 office & parking lot. Since there's nothing to see there, might wanna block the door to the office off so that new players get the idea they need to go to the left... especially if you're not adding direction arrows.
