Uncharted is cheaper, get that instead.
Honestly, my save file says I'm 18% through and I've done almost nothing. The gameplay consists of approaching a situation and deciding if you can stealth kill someone, then shooting the rest of the enemies. If there's a ladder that needs to be picked up and moved somewhere, you'll have to do that too. It's kinda awkward control wise, but it's mostly the right button is instructed. I'll play it through because the story is alright and the graphics are really good, but something needs to improve in my experience for it to come close to living up to the hype.
