Absolutely can't wait for this game to release in March of 2013. It will be the first game in the series to receive and M rating.
I love survivor games and I love the Tomb Raider series. Lara Croft is just so badass. She wasn't always the elite free climber she is now, though, and this game will focus on her journey of becoming a hardened survivor. You will have to hunt and survive on the island where your boat crashes. The island also harbors dark secrets and dangerous natives that don't take too kindly to guests. This game will be very 'real' in the sense of fear and survival.
I believe you can preorder it on Steam, Amazon, and some other places for about $40 - $50. There are a few DLCs that have already been announced and more to be released a bit later.
Honestly, this game looks fantastic and I'll be playing it the moment it's released.
