Welcome to another Tomb Raider "Survival Guide" dev diary this week—the last one divulged a ton of info about the game's opening moments and various systems, like upgrades and others.

Today, we explore exploration in Tomb Raider. It looks like Tomb Raider will feature a Metroid-like system of upgrades and exploration incentives, where new equipment and abilities allows you to discover more rewards when you return to previously visited areas.

That should help pad out the length, but we're not complaining. There's plenty more info in the video, so check it out and let us know what you think.
