Upstairs Downstairs

A co-operative map featuring four puzzles, set in an abandoned Old Aperture test sphere. The puzzles get progressively more difficult. None of them require ninja moves or reflexes - you simply need to have a good think together! The map is meant to be hard, forcing players to think and act collaboratively. Feedback is, as always, very welcome.

Absolute brilliant map!

So many exploits. Just think out of the box and you can skip all the rooms except for the last one, which is really simple.

The water effects look very cool. There are places where the characters can get trapped. We got seperated trying to go around the timed switch room that didn't seem to work. We threw the switches in order and nothing happend...we tried to go around and got trapped in seperate areas...

I may have beaten your map in about 45 seconds with a little more direct approach.
Who needs portals anyway?

Thanks for making the map

Hard map (that means good), but is boring. 8/10 from me.

We have no idea how to solve the room with the goo, that second one. But (after using an exploit), we cleared the rest of the chambers.

Out of the 200+ co-op map I've played so far this one was definitely the most challenging. The third test really had us pulling our hair. ;-) Fantastic work, thank you very much!
