If you guys want an honest to God take on this, here it is:
Setup:
The world ended... No one knows why, but reality is broken and the dead can roam the world of the living. This happens to a highly advanced civilization that had automated away most jobs. So, most people are soft and afraid. Even to walk outside.
Bridges is trying to step into the shoes of the US govt', trying to connect everyone back together through something called the Chiral network. How it works and stuff is detailed in the game.
Gameplay:
It's very slow. Let's get that out of the way. There's a clear focus on traversal over combat or even stealth. The game features a brand new gameplay system based on terrain, stamina and cargo. So, basically, instead of avoiding gun fire and anticipating where enemies will come from you'll instead focus on watching your step, making decisions of using or not equipment you brought with you and reacting to random shit that happens to you: Timefall, BT's, MULE's, coming up on a cliff with not enough ladders, descending a mountain loaded to the tits with cargo and no rope or stamina....
Shit like that.
If you can immerse yourself and roleplay while playing, you'll be in heaven. If you're looking for something to min-max, there's that too. you can simply challenge yourself by always travelling with maximum cargo. This makes the game very difficult in all aspects: combat, stealth and traversal.
