After getting 5 stars I destroyed all the elevators to trap the guests in the hotel, but then I made the mistake of firing an employee. Since there was no way for the employee to get out the game froze.
Why do all comments relating to FoD get so many minuses? It's good multiplayer alternative to the steambirds games, especially if you get bored of/need a break from endless waves of planes trying to destroy you. I'm sure the steambirds multiplayer game will be better than FoD but until that's out, I suggest trying out Fly or Die.
