UPDATE 6.00 pm: Metro publisher Deep Silver has confirmed that Metro Redux, the next-gen rendition of the Metro games, is in fact real.

The publisher sent Eurogamer the following letter explaining the situation:

A short letter to the Metro fans - past; present; and future...

Metro Redux. You may have heard of it... even though you probably shouldn't have!

We could issue a 'We do not comment on rumour and speculation' statement and pretend this never happened. They're pretty boring to read. They're also pretty boring to write.

So we're going to comment on rumour and speculation instead.

Is Metro Redux real?

Yes. We never made any secret of 4A's desire to bring Metro to the latest generation of console hardware.

But what you saw leaked was taken from an old, internal planning presentation, containing some nuggets of truth but a lot of hypothetical ideas and place holder material.

(Eagle eyed fans will recognize the artwork on the 'packshot' as the art from the original Russian edition of the Metro 2033 novel. And that 'logo' is just the old Metro 2033 logo with the '2033' scrubbed out and 'Redux' added... )

As you can see, we're not quite ready to reveal 4A Games' first next-gen console project, but we will be making an announcement this side of E3.

And we think the reality is a lot more exciting than the out-dated material that got leaked shows, and we're itching to share it with you. Just not yet.

ORIGINAL STORY 9.30 am: New images have emerged revealing what looks like PlayStation 4 and Xbox One versions of atmospheric shooters Metro 2033 and Metro: Last Light.

The images, below, show off a game called Metro Redux, and is listed for the PC, PS4 and Xbox One. It's supposedly out in July and is developed by the series creator 4A Games.

It includes Metro 2033 Redux and Metro Last Light. There's also mention of a day one DLC token, soundtrack, art cards and limited edition packaging.

The images first popped up on Italian website Everyeye.it, but were removed - not before AGB picked them up.

We've asked publisher Deep Silver for comment.

Metro 2033 released on PC and Xbox 360 in March 2010. The follow-up, Metro: Last Light, launched on PC, PS3 and Xbox 360 in May 2013.
