A new trailer has been unveiled for the upcoming Doctor Who: The Eternity Clock game which is coming out for PS3, Xbox 360 and the PlayStation Vita.

The new trailer shows actual gameplay for the game and it looks as if the developers have gone for a retro feel with the side-scrolling platform feel making a refreshing change and echoing that of the recent Tintin title.

Elsewhere it's clear that a lot of attention has been put into authenticity with each character looking picture perfect with some characters (we're looking at you Alex Kingston) having been given an outfit that screams 'The Avengers'.

Doctor Who: The Eternity Clock see's Matt Smith's Doctor travel across space and time as he and River Song battle through the universe to try and save Earth.

Players will be able to play both characters and will have to master the intricacies of time-travel where even the smallest decision in one time will have major consequences in future levels adding an entirely new aspect to conventional gaming.

The game has been written in collaboration with the BBC Wales team that work on the series and will feature full voice-acting from the entire cast. The Eternity Clock is just one of three Doctor Who games planned in the series.

All in all it looks to be shaping up as a brilliant platformer and with the release for PS Vita as well it'll be great to see those graphics really shining through on the handheld.
