Portal 2 Map - The Halls of Menoetius
This is a portal 2 co-op map that is quite challenging. It is one very small and self contained puzzle that involves no glitches, weird portal maneuvers or anything a standard portal gamer would not be able to do.
The map uses portals but interestingly not through the portal gun. The Puzzle can be solved, however it will require teamwork and brain power.
