Check instore for details. A decent selection of Xbox 360, Wii, PS2, PSP and DS. From what I can remember, these games were in the offer.
Xbox 360 - Virtua Fighter 5, Call Of Duty 3, Overlord, Project Sylphed, Pro Evo, and many more.
Psp - God Of War, Every Extend Extra, Gunpey.
DS - Elite Beat Agents, Starfox.
This is a really good offer, especially since you can get God Of War which is still retailing for full price in many stores.
