Pre-ordering Rockstar's latest sandbox crime game, Grand Theft Auto 5 ,
on Xbox 360 through the Microsoft Store
will nab you some Xbox Live Marketplace credit: 1,600 MS Points worth, or $20 in real-world money.
Microsoft issued an update
converting MS Points to real currency on Xbox 360 yesterday. This coupon code, despite being in the old MS Points currency, is still valid after this update.
Grand Theft Auto 5
is set to launch on Xbox 360 and PS3 on September 17. Rockstar parent company Take-Two expects the game will generate $600 million in revenue
– and maybe you'll spend that bonus $20 on the inevitable DLC.
