Lol, love how there's Polybius arcade machines in this game.

Of course most of the arcade machines you find are other Wolfire games XD Overgrowth of course, but also Black Shades, Depserate Gods, and Lightning's Shadow. No GLFighters or Lugaru tho! Strange.

STILL 99% certain that's an abstergo logo in the ground floor of the lift lobby rooms with the hospital gurneys.
