Another trailer that does nothing to shed light on exactly how this game will play.
I'm getting so tired of these posts. We've known the general gist of the gameplay loop ever since the E3 2018 trailer and now we know exactly how everything comes together with the BRIEFING trailer in the OP.
You play as Sam 'Porter' Bridges, a courier for the United Cities of America (UCA). You deliver cargo and other things to fractured settlements scattered across a post-apocalyptic United States through Chiral Network Terminals on behalf of the company 'BRIDGES'. Cargo plays a major factor in how you traverse the world. Carrying too much makes you susceptible to tripping and potentially damaging your load. You have constantly manage your Sam's weight and balance which makes even basic things like walking a challenge.
You can equip various 'skeleton' enhancements to help traverse the world easier such as the power skeleton which lets you carry more cargo and equipment or the speed skeleton which makes you walk faster.
Sam is asked by Die-Hardman (commander of BRIDGES) and Amelie (President of the United Cities of America) to finish the job of reuniting America she started three years ago after a series of supernatural phenomena and explosions known as the 'Death Stranding' rocked the entire world and destroyed modern civilization, bringing about interdimensional beings known as 'BTs' or 'Beached Things' that are stuck on Earth and roam the wastes, looking for humans to kill. This has naturally caused civilization to return to a sort of pre-industrial society in all but technology, with people forming small settlements that keep to themselves instead of coming together as one cohesive unit.
Die-Hardman also wants Sam to save Amelie in the process after she was captured by Higgs and the Homo Demens who control Edge Knot City (Los Angeles) and oppose the UCA's goal of reuniting America. They want to secure the independence of Edge Knot City and unite the various settlements through fear and force.
Sam reuniting America involves trekking across a barren wasteland forming 'strands' with settlements that are eager to join the UCA by going up to Chiral Network Terminals and connecting your Q-pid to them. While you do this, you need to be wary of the many dangers the world has to offer such as BTs and Homo Demens. Dying in this game places you in a sort of purgatory state where you have to find your way out from the 'other side' and wake up. Once you do, this forms a permanent crater in the spot you died in which has a severe impact on the game world.
It really isn't that hard to grasp.
Wait I thought edge knot was the center of the U.S and no one has made it past that? Amelie was capture in Edge knot.
Edge Knot is on the West Coast, it's near-future Los Angeles according to Eurogamer. You're going from East to West like they say in the video.
