Evil Underground (Coop)

GLaDOS sent you into the deep underground to solve a test she recently discovered.
This is my first underground testchamber, I hope the visuals look okay for this first time.

Difficulty: Hard (8/10)
Estimated time to complete: 10 - 30 minutes

This map contains 2 testchambers, but the second one is only solvable with the help of the first chamber (but you'll see it ingame). To warm up, the first testchamber is quite easy to solve, but the second testchamber is going to be a tough one. Good luck with these tests!

Have fun!

If you liked this map and want to check out my other coop maps, then you can follow these links:

Reparation Forces (Coop) is a medium - hard difficulty map which contains a tough light bridge puzzle and some medium stuff. Calculate around 30 minutes to complete this map.

Night Turn (Coop) is a very long map, but also a great brain teaser! It contains 8 different puzzles and each of them requires unique solving strategies you normally do not need to do (in comparison to other puzzles). No ninja skills or something like that required. Calculate around 45 - 75 minutes to complete this map.

Disc Puzzle (Coop) is a map I made in cooperation with theLUCKYfighter. As the name says, it is going to be a puzzle with the disc you know from the coop courses. Calculate around 30 minutes to complete this map.
