This is a 3 pack of the promotional Xbox 360 Burger King games that were released only in the USA in 2006.
They are Sneak King, Ninja Burger and PocketBike Racer and originally cost about $4 each with a value meal.
They don’t seem to work on PAL Xbox consoles which is disappointing since other bloggers or sites said they were compatible (or maybe they just said worth importing?) I’m not too fussed but would have really liked to have played these. Oh well.
