It's not a bug in the game's code, it's a bug in your moral code

I like this novel approach to piracy protection :

It's not a bug in the game's code, it's a bug in your moral code

Anyone who attempts to direct Batman using the "glide" button finds that the feature has been disabled, causing the Caped Crusader to plunge to his death.

One gamer who got his hands on an early copy of the PC version, which is released this week, reported the apparent bug in a hastily-typed post in the game's official forum, complaining that Batman kept dying in a cloud of poisonous gas.

"I've got a problem when it's time to use Batman's glide in the game. When I hold , like it's said to jump from one platform to another, Batman tries to open his wings again and again instead of gliding. So he fels down in a poisoning gas. If somebody could tel me, what should I do there," he wrote.

But rather than sympathy or tips from other players, he received a ticking off from an employee of Eidos, the developer behind the game.

"The problem you have encountered is a hook in the copy protection, to catch out people who try and download cracked versions of the game for free," he wrote.

"It's not a bug in the game's code, it's a bug in your moral code."
