Cyan Contest Idea Number G

Sooo... *Artoveli hosted a contest through most of August and September, and I seemed to have missed it due to horrible timing in the life department, but what can I do?

So here is Contest Entry Number G. That is right, Number G. That means there are A through F that are unfinished/scrapped/not-even-started.

This is a response towards Portal 2, which looks like it will be awesome, but it will also feature Co-op play. And thus idea was born. There is actually more planned for this idea, but who knows if I will ever get to it.

You probably need some knowledge of Portal for any of this to make sense.

Cyan belongs to *Artoveli
Rio belongs to me
