In the first chapter of my trilogy's first act introduces the protagonist, other major players in the series and the series' setting. The bulk of my trilogy takes place in a city that has been ravaged a massive explosion and sealed off from the outside world by a shadowy military organisation called S.W.O.R.D, who are dead ringers for Blackwatch from [PROTOTYPE]... if Blackwatch was a peacekeeping organisation that answered to the UN Security Concil, significantly less psychotic and run by card-carrying Laconophiles.
In this chapter, the audience learns that S.W.O.R.D has disabled all forms of wireless communications such as the Internet and cell phones. A large fleet of ships blockades the city's harbour and extends along the surrounding coastline, while a strictly enforced no-fly zone stops civilian aircraft flying over the area, and a massive wall prevents anyone from entering or exiting the city. The first chapter sees the protagonist navigate his way through the city and reveals that vast ramshackle slums have sprung up in the blast's wake where poverty, severe malnutrition and disease are an everyday reality for the city's denizens, in spite of S.W.O.R.D issuing humanitarian aid.
It's revealed that S.W.O.R.D has also established various checkpoints throughout the city and the Krypteia (S.W.O.R.D's intelligence-gathering division, which consists of operatives skilled at hiding within a civilian population) acting as a secret police (who follow the protagonist and his brother over the chapter's tenure).
I want to get all of this across to the audience in the first chapter without informing them in a rushed manner without putting in any effort into how I do it. One of the many reasons I detest The Hunger Games (along with its soulless prose, flat mentally stunted characters, unsubtle social commentary, heavy-handed symbolism and nonsensical worldbuilding) is that Suzanne Collins doesn’t know how to show rather than tell. For example, in the first book's opening chapter, Katniss tells us that District 12 is a shithole rife with poverty and disease in a huge info-dump, yet we never see anything to support this. It gets worse in Catching Fire when we are told that many anti-Capitol riots are taking place across Panem during the book's start, yet we hardly see any of these riots save for one that occurs in District 8.
How can I introduce my reader to my setting in a spontaneous manner without violating "show, don't tell"?
