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.

Excellent concept and puzzles. Unlike other Portal mods (such as Portal: Prelude), I love how this game was actually puzzle-based, instead of skill/time based. I like a game where you are forced to sit down and think. I completed this game checking the walkthrough only once, so the difficulty was spot-on, in my opinion.

My major complaint comes from the story and glass shooting objectives. While the story concept was brilliant, I feel there is so much potential gone to waste. I didn't completely understand why Chell died (although, I assume she 'self-destructed') and the backstory was underdeveloped. Still good, though. Second, I didn't like the glass shooting objectives because I felt like I was cheating the system. It is okay outside the chambers, but not inside.

All in all, really fun mod. Difficult puzzles keep the game popping, but an underdeveloped story drags it down. I'd highly recommend this mod. One of the best I've played!

I really think this is one of the best mods I ever played (and I played almost all Portal mods released here in ModDB).
The chambers here are the most well designed, beautiful and epic chambers I ever seen in a Portal mod. I particularly loved the "Vertigo" chamber. It's so HUGE and cool!

The only item that disappointed me and made me rate Gamma Energy 9 and not 10, is that there's no new storyline. Obviously what happens on the end is different from what happens in Portal, but no custom GLaDOS voice was used, and this is very sad because the rest of the mod is perfect.
The new elements like the explosive barrels and the breakable glass of the observation rooms are lovely and creative.

Everybody that beated Portal at least once must play this mod!

(PS: I had to check the walkthrough two times... O.o)

I played this mod about 2-3 months ago.

This mod was amazing. At many points this mod is at least as good as the original levels of Portal. The concepts were original and the ideas interesting. However, some things were very annoying like using that signage to crush some of the glasses. I got stuck there for quite a while and it took me ages and many quickloads to get that to work because that sign totally bugged around. Overall this mod is worth the play though!

I recorded my completed blindrun, maybe anyone will be interested in it. I've split it into 6 parts to be more handsome:

Part 1: Youtube.com
Part 2: Youtube.com
Part 3: Youtube.com
Part 4: Youtube.com
Part 5: Youtube.com
Part 6: Youtube.com

I liked this mod. It had good balance between extremely hard and extremely easy. Only complaint from me is the Escape chambers felt too HL2-like with all the props.

Great mod. Enough levels to keep people interested for a while. I love the levels where you had to get like 5 boxes to get to the end. The only problem with it is that since the energy ball launch balls at a certain time, you could have multiple balls flying around, and the advance levels were too hard for me.

The game is great, but the escape routine, the final boss and the recycled quotes and textures turn it away from perfect.

Amazing puzzles that were more fun then the actual game. So additicing I beat it in one seating. Only advice is the final boss is just kinda meh, it would have been better if it would have just ended.

loved the maps, some even caught me off guard for a while.
ran into some bugs, most just by chance and weren't repeated.
all in all great job
