Guardians: The Last Day of the Citadel, a hack-and-slasher by Drakkar Dev, has just landed on the App Store.

And with 3D graphics powered by the Unity engine, it certainly looks the biz.

You play as Loreena, a female warrior with a serious axe to grind. Your home - the Citadel - has been invaded by the demonic Vash and you've got to escape.

Guardians: The Last Day of the Citadel also boasts an original soundtrack, a full campaign, and 'cinematic-style' fight sequences.

If you fancy a piece of this slash-'em-up action, download Guardians: The Last Day of the Citadel now on iPhone for $4.99.
