Gamma Energy visits the Aperture Science East facility, built after GLaDOS gained sentience. The goal was to create a facility where GLaDOS' research could be examined and tested without harm to employees or other people who actually... mattered, without her knowledge. Pick up a prototype Portal Device and try not to die.

Description

Here's the mod as a 7Z archive. A ZIP version is coming soon. Windows users: extract and put the gamma_energy folder in your steam/steamapps/sourcemods folder and restart Steam. Mac instructions forthcoming.

This mod starts out really good, with challenging puzzles and it's really fun to play. But as I progressed through it, the levels became increasingly harder as expected, but it got to the point of where I was getting really frustrated tired of things. I ended up having to cheat so that my blood pressure would go down a bit. Overall it's a great mod, but some parts are hard as hell.
