In case you missed it, Xbox recently announced they've added two more Tomb Raider titles to the growing list of backward-compatible Xbox 360 titles for Xbox One. Tomb Raider: Legend and Tomb Raider: Anniversary are now playable on Xbox One either with an Xbox 360 disk or by downloading from Xbox Games on Demand.
Underworld has been available on Xbox One for about a year. (You may have seen me playing the expansion packs, Beneath the Ashes and Lara's Shadow, on Twitch last fall during Extra Life.) The arcade adventure Lara Croft and the Guardian of Light, originally released in 2010, also came to Xbox One in February 2018.
If you've never played the Legend trilogy, this is a great opportunity to revisit Lara's roots. Follow these links for more info and complete walkthroughs for Legend, Anniversary, and Underworld. If you're up for a fun challenge, solo or with a friend, Lara Croft and the Guardian of Light is an explodey good time!
