Gordon Freeman, complete with Gravity Gun, and Ezio from Assassin's Creed 2. For a minute we thought we'd miraculously spotted former Joystiq blogger (and amateur Gordon Freeman lookalike) Ross Miller, and were set to pounce on him, but thankfully we noticed at the last minute and averted disaster. Click Gordon for a larger version, which includes his employee ID, and head beyond the break for Ezio.
There's more cosplay going on here than at a LARP convention, and we'll be bringing you a lot more. Click through for Ezio and his blades, and stay tuned.
