This is a condensed story overview with notes on the Cloudburst and Deathstroke tank fights, not a mission-by-mission walkthrough. The story summary follows Wikipedia; the boss and mission details follow Gamer Guides and GamePressure, as listed under sources. Spoilers follow.
On Halloween, Scarecrow threatens Gotham with a new fear toxin and the city is evacuated. Batman tracks him to Ace Chemicals, where he limits the blast of Scarecrow's toxic bomb and learns of a militia led by the “Arkham Knight”. Batman has also been infected through a transfusion of the Joker's blood, which makes the Joker appear as a hallucination that can briefly take control of him.
The Batmobile has two modes: Pursuit for travel and driving challenges, and Battle, in which it becomes a tank with 360-degree movement, anti-tank missiles and a cannon. Wikipedia lists upgrades including more missiles, an EMP device and a “drone virus”. The Gamer Guides walkthrough of the Miagani Island tunnels, for instance, offers a choice at Wayne Tower between a CPU Virus upgrade, which lets you hack an enemy Drone Tank into a temporary ally, and a Weapon Generator MKIII, which slightly boosts weapon damage.
Scarecrow recruits Simon Stagg to build the Cloudburst, a dispersal device for the toxin, and the Arkham Knight takes it from Stagg's airship. Batman finds Barbara Gordon (Oracle) at Scarecrow's hideout, where she appears to shoot herself; this is later revealed to be a hallucination. The Arkham Knight then floods the city with toxin. Batman destroys the tank carrying the Cloudburst, and Poison Ivy empowers an ancient tree that neutralizes the toxin, saving Gotham at the cost of her life.
Batman pursues the Arkham Knight to rescue Gordon, and the Knight is revealed to be Jason Todd, the former second Robin, who escapes after refusing Batman's help. Scarecrow escapes with Gordon, attacks the GCPD and kidnaps Robin. Batman surrenders and is taken to the ruins of Arkham Asylum, where Scarecrow unmasks him as Bruce Wayne on television and repeatedly injects him with toxin. Inside Batman's mind, he locks the Joker away. Todd then rescues Batman, who subdues Scarecrow with his own toxin.
Batman activates the Knightfall Protocol to protect his loved ones, then returns to Wayne Manor, which explodes. In the epilogue Gordon is mayor and attends the wedding of Oracle and Robin; the game ends with two muggers confronted by a nightmarish Batman-like figure in an alley. Wikipedia says the full ending requires 100% completion, which includes the Riddler's 243 optional challenges. Community guides report that the Knightfall Protocol can be started after at least seven of the fourteen Most Wanted missions, with a more complete ending after all fourteen, all Riddler trophies and defeating the Riddler; we could not confirm those exact thresholds from an official source.
The Most Wanted missions can be attempted at any time and feature well-known Batman villains. Penguin's weapons-dealing operation is dismantled in the Gunrunner mission (with Nightwing's help tracking weapon vans to caches), which is separate from Campaign for Disarmament. Deathstroke appears in the Batmobile fight described below.
⚔️ Boss Guides
Cloudburst Tank (Arkham Knight, second encounter)
Where and setup
The fight takes place on Bleake Island. Arriving raises the bridges, and they stay up until the boss is defeated. The island's Cobra tank count jumps to seven: six standard Cobra Drone Tanks plus the Cloudburst (Gamer Guides).
Strategy (per Gamer Guides)
Isolate and destroy the six Cobras first by shooting the glowing section on their backs, using alleys, ramps, sewers and tunnels to avoid their lock-on. Approach the Cloudburst while its vision cone points away from you and scan it in Detective Mode to reveal four weak spots. In phase one, sneak up, shoot a weak spot, then run: the Cloudburst enrages and chases you at full speed firing lasers, so break line of sight and avoid the holographic landing circles. After four weak spots, phase two begins: the mega laser is disabled and you shoot the exposed orange core while it throws grenades and fires up to three lock-on missiles. Kite it around a building for cover, use the machine gun to shoot down missiles, and fire the main cannon whenever it recharges.
Deathstroke (Most Wanted)
Where and unlock
According to a Twinfinite guide cited in search results, the fight requires Own the Roads, Occupy Gotham and Campaign for Disarmament to be completed, and takes place at Grand Avenue on Miagani Island, where the bridges are raised until it ends. It is a Batmobile fight: the island has six Cobra Drone Tanks, five standard and one being Deathstroke's. Only the broad format is described here because we could not verify attack details.
