What happens when you install GlaDOS into the Vocaloid Hatesune Miku? The worlds greatest virtual diva becomes the worlds greatest virtual antagonist. Based on the Portal Vocaloid internet meme, Portal: Vocaloid edition hopes to make what is now a popular concept into a gaming reality.
I'll give it an 8 out of 10. Why? Because I feel my mod is inferior to this. -_- I am jealous. Good game overall.
