| This achievment is most easily done on your first playthrough in the mass and velocity course. There are many locations in the course where you go through an infinanite fall with two portals, one on the floor and one on the ceiling, where the ceiling is low. You can simply hit up to gesture twice and this achievment will pop. If you have already completed the game and are returning to get this achievement, simply follow the 2 guides below for the excursion tunnel course. |
