You must do this when you buy the game. You must.

Readers who follow our own James Newton on Twitter may have seen this Tweet last weekend, which implied our hard-working and handsome News Editor (Okay, that's enough — Ed) was already in possession of Legend of Zelda: Ocarina of Time 3D. As it happens, the mystery box in his hand was not Link's upcoming four-dimensional adventure, but rather the Zelda pre-order incentive for UK gamers.

Instead of the cardboard sleeve some were expecting, the bonus is actually a sealed software box just like 3DS software itself, with the poster included inside.

The sleeve bears the game's North American box art in a shiny gold finish, not unlike the first release of Legend of Zelda: Wind Waker. The rear shows screenshots, game information and even bears a bar code, meaning it can be used as a complete replacement for the game's original cover.

As for the poster, one side depicts Link and Epona galloping across the countryside while the other shows Link and Ganondorf engaging in classic combat. Both sides of the poster can be seen in the gallery below.

For those interested in what's depicted on the sleeves inside, Rupees of various colours poke through the 3DS box gaps, with a picture of Young Link looking thoughtful hidden away in the corner.

With 17 days to go until the game launches in Europe, there's still time to nab one of these bonus items when you pre-order Legend of Zelda: Ocarina of Time 3D at GAME.
