Freak Unique is an Honorary Arcade League challenge in TimeSplitters Future Perfect. You can unlock Hans with a bronze.

Strategy

You are Hans and are against the red team (Mischief, Stumpy and Mister Giggles and the green team (Oleg, Vlad the Installer, and Leonid). When you start, off to the left is the green team and up straight up the stairs is the red team. Since the green team is tougher, run up and take down the circus folk, and any green guys you run into. I found it much tougher to go fight the green team head on, since they are all equally challenging and only Mischief is any good on the red team. Either use the Machine Gun that you start with or the Shotgun. Either way, the mission can be a bit difficult, since the green team will get a lot of points, but it still shouldn't take too long to beat.
