Thanks for the link. I read some of it and I will continue playing it as soon as I have time.Well, the best advice I can offer for finding those additional treasures is:
look at an obscure corner, a place that's hard to get to, then think of a way to get there.
Mean, aren't they?
I find this site to be good for walkthroughs:
Tomb Raider Underworld (Tomb Raider Chronicles)
I'm disappointed about the xBox (yet again) getting the bonus perks and PC/Playstation players not.
According to the site info, xBox players get 2 bonus levels, Beneath The Ashes and Lara's Shadow.
You mean like Sylvester Stallone? Only it's Standalone? LOL!!mmmmmmm, maybe's it's like a random person (standalone) not involved in the company, that offers a download of the levels.
