At one point in the demo, Lara and Totec set out to enter a Spider Temple by collecting four floor plates. While doing this, they encountered a special Challenge Tomb, which Crystal D said was only one of many optional puzzle tombs. Upon release, these tombs will come in three difficulty levels, and will reward players for straying off the main quest line by granting them special items. Once the Challenge Tomb puzzle was solved, Lara and Totec returned to the Spider Temple where they were attacked by huge, nasty spiders. They fought these off using anything and everything, including big spiky stone balls that could be rolled into and over the oversized arachnids. We were told these handy spheres could be found all over the ruins and could be used both as weapons and as a means of overcoming obstacles like fire barriers.

Speaking of fire, the graphics in the Guardian of Light demo were pretty darn good. No wonder, since the game was made using the same engine as the last three Tomb Raider titles, and as such, has the benefit of the same lighting and physics. The Spider Temple level we got to see was especially cool, since it was designed to be vertically navigated and gave amazing vistas of the paths far below (paths which weren't just background art—the heroes actually traversed them later on).

Lara Croft and the Guardian of Light promises to be one of the more impressive looking downloadable titles this year, as well as one of the most fun, with its emphasis on co-op gameplay. The game can be played solo or with a partner, either on or offline and offers more than six hours of gameplay. Until the return of Tomb Raider, look for your Lara fix in The Guardian of Light this summer on XBLA, PSN and PC.
