Map by Basteh :]
My first map for Portal2, lots of try and error style mapping.

This map is less puzzly but involves strafing and the right timing.
Difficulty: medium
There is also a hidden Companion-Cube! Hint: Look out for the red light and try to get there.
If you manage to escort the Companion-Cube to the End and place it on the Button you will be rewarded!

To install:

Go to Steam\steamapps\common\portal 2\portal2\maps and put the .bsp in there

Start up Portal 2, start a multiplayer match, invite your friend, while connecting to the Hub or in the Hub,
go into the console and write "changelevel mp_coop_jumpingjack" and have fun!
