Specifically, the video focuses on the upgrades made to Lara Croft's physical appearance, which are detailed by Tomb Raider executive producer Scot Amos.
Set for release on January 28 in North America and January 31 in Europe, Definitive Edition features plenty of new graphical flourishes, but nothing fresh in terms of gameplay or story elements.
Amos told CVG: "One of the very first conversations we had was whether to include stuff we'd actually designed for the 360 and PS3 versions which we changed or just didn't get round to at the end of the day for one reason or another.
"We looked at the possibility of adding more side tombs, adding a few extra pieces, and fleshing out any pieces of story we could go further on. There was a debate internally and ultimately we came to the conclusion that we already had the story we wanted to tell."
Tomb Raider Definitive Edition "looks to be a more technically accomplished version of the original that brings it closer to the superior PC version", we said in a recently published Tomb Raider Definitive Edition preview.
