Sounds cool. BTW good expedition script writing. Sounds cool for Sam to find a lost city and escape Nate's shadow. Especially since that city will be submerged underwater. It would likely open a whole new set of weapons and combat system or at the very least more boat fights.
2. The game nearly always had you in the middle of some action whether it had you running towards or away from something it always kept you moving. That made it awesome for me because first one was awesome but compared to Uncharted 2 Uncharted 1 seemed a tiny bit less like an action-packed 3rd person shooter and more like Nathan Drake's camping simulator 'cause throughout nearly the entire first game I got by with camping in one spot for an entire battle sequence.
