Insomniac Games has expressed frustration that the PlayStation Vita version of Ratchet & Clank Q-Force that Tin Giant is working on has not materialised yet.

In a post on its official Facebook page that has since been deleted, Insomniac said that even though the game has been out on PlayStation 3 since November 29, it was not authorized to share any updates on where the Vita version was.

Polygon managed to grab the text before it vanished:

Hey everyone,

We know you’ve been asking about and waiting for Full Frontal Assault for Vita.

Insomniac cannot make any comment about the game. We have repeatedly asked Sony and Tin Giant for an update to share with our fans. They have not provided any update we are allowed to share.

We are sorry for any disappointment, but there is nothing we’ve authorized to release publicly. Trust us in that we share your frustration, and have been passing your comments on to Sony, we also advise you contact Sony directly to share your disappointment and frustration.

As soon as they give us an update we can share with you, we will.

Thanks,
IG

In his 6/10 review of Ratchet & Clank Q-Force on the PlayStation 3, Gameplanet's Gareth Talbot praised the game's humour and wide array of weaponry, but condemned its poor implementation of tower defence mechanics.
