Rexaura is a mod for Portal based on high energy pellets and several new mechanics surrounding them.
This mod is really incredible. Great and funny new voice lines and elements, interesting music, beautiful design, fantastically detailed environment, and awesome challenging puzzles that will really test your quality of thinking. I'd say that same good as your previous mod Portal Pro, really great job Mevious and thank you very much for this mod, and I highly recommend to play this!
Dear Mevious! After your brilliant Portal Pro I started to believe that God had created some people in his own image and likeness. Now you have proven it again.
The second bonus level and the way to get the second secret are absolutely godlike.
You have my respect and almost religious admiration.
Rexaura is pretty much the best Portal mod in existence. Put simply, it's a bunch of Valve quality test chamber maps with a continuation of the wry and nasty sense of humor that ran throughout Portal.
If you liked Portal and want more of the same, this should be your first port of call.
