We've seen artist TwoHornsUnited come up with some Portal referencing gas masks before, but this one is even more creepily awesome.
I also get the impression that I would look like a Valve-inspired Transformer if I wore that, and then my brain goes on from there to invent wild action sequences where I'm flying through the air shooting lasers at Decepticons while the Autobots cheer me on as their secret weapon and savior.
Is that the door right there? I'll just let myself out.
