Fancy getting 1000G when Lara returns? If so, you'll need to sharpen up those competitive skills.
Dedication and an awful lot of grit will be needed to maximise Achievement points from Crystal Dynamics' title. Eidos Montreal are in control of the game's multiplayer portion, and have been awarded a fair chunk of Achievement progress to play with.
So, what does this actually mean? As reported by X360, you'll have to reach level 60 during online play, unlocking the "True Commitment" 30G score.
Whether or not this harks towards Seriously 3.0 levels of difficulty remains to be seen. Either way, 250G is waiting online.
