The best Tomb Raider since the first, too bad it's not a lot longer.
The new non-grid gameplay system is excellent. Moving Lara around is so much easier and faster than in previous installments. The graphics are amazing so long as you can turn on next-gen graphics. The fighting isn't much improved but Tomb Raider isn't really all about fighting anyway.
The level design is amazing and feels so much more organic than all of the other games. The unlockable content is pretty cool, but it wasn't enough to make me play through the levels again to find the secrets. Overall I'd say this is a great game but a short one. If you've lost hope in the Tomb Raider games, then look here, this is how Tomb Raider was ment to be.
