If we had our way, every iPod game would make use of your own music in some innovative way. Square Enix's new title is a good example: it's called Song Summoner: The Unsung Heroes, and it's out today on the iTunes Store.

It's a tactics-based RPG where you play a young buck called Ziggy, who has to rescue his kidnapped brother from the nefarious Mechanical Militia.

How? By creating warriors ('Tune Troopers') to wade into battle on your behalf. And here's the cool thing: you create them from your own songs stored on the iPod.

Yes, you can send Amy Winehouse's 'Rehab' tottering into battle, or find out just how The Automatic's 'Monster' copes when there really are monsters coming over the hill.

Better still, when you play these songs outside the game, they'll power up their Tune Troopers inside it.

It sounds great, and a good companion to the recently released The Sims DJ, which made similar use of your own tunes. Song Summoner: The Unsung Heroes is available now for £3.99.
