Thanks to good people of Reddit, I have a copy of Alpha Protocol.
And I'm disappointed :(
First of all, the PC controls are horrible. Especially the dialog options.
Then I switched to the gamepad. Guess what? Those who made this game haven't tested it with two identical gamepads. Like you have all sorts of trouble with Assassin's Creed games, but more subtle and annoying. It works fine except you can't choose anything in radial menus (skills, weapon, etc.) Because the game use the analog stick from the 2nd controller. And you can't do anything about it. WTF?
