Hardly news, we know. But Portal 2 fan Gary Hudston went looking for a level designer to help him propose to his girlfriend Stephanie through his favorite game. Not only were several unique maps created for this most epic of marriage requests, but Ellen McLain reprised her role as GLaDOS specifically for the project. The end result lies above. Be warned, once you view this video, be prepared to realize your own past/future proposal inadequacies in comparison.
The Gary Hudston Project is the work of TopHATTwaffle (Doug Hoogland) and Miss Stabby (Rachel van der Meer). The components to recreate the level featured can be downloaded here.
