Here's another quick update: the gold artifact from England. As Lara's exploration into the true Excalibur myth progresses, she must break into a run-down side-show-esque King Arthur museum in England. Deep below the museum lies the true grave of the legendary King Arthur, and another piece of Excalibur. These ancient crosses are scattered throughout the ruins.
I've already begun work on a lot of the suggestions from the ShoutBox, so stay tuned!
