In Batman: Arkham Knight, protecting Gotham City from the Arkham Knight's occupying militia requires players to systematically dismantle various localized threats. Among the most volatile side-campaigns is the Campaign for Disarmament, which tasks the Dark Knight with tracking down and neutralizing explosive devices buried beneath the city's streets. Defusing these hidden threats on Bleake Island is essential for unlocking the final confrontation with Deathstroke and securing total completion.

The Ursa Major Bomb Location

The first major explosive device on Bleake Island can be located in the northern commercial district known as Chinatown. Specifically, players need to navigate the Batmobile near the Ursa Major building intersection to trigger the militia tracking signal. Once the virus upload begins, you must defend the position from incoming drone waves using your heavy weaponry equipment.

Surviving this initial encounter relies on managing your position within the narrow alleyways surrounding the intersection. Utilizing the Batmobile's dodge thrusters ensures you can avoid incoming missile indicators while maintaining a steady lock on targeted hostile units. Successfully uploading the bypass code will trigger a controlled explosion, completely neutralizing the localized danger.

The Panessa Studios Bomb Threat

Another dangerous device is located near the eastern coast of Bleake Island, positioned closely to the entrance path leading toward Panessa Studios. This location features highly aggressive drone configurations that will deploy specialized tracking mines to compromise your combat mobility. Approaching this zone with a fully upgraded missile barrage system can significantly ease the defensive burden.

The tight corners near the studio facility require careful deployment of your cybernetic countermeasures to hack high-threat targets quickly. Maintaining structural cover helps isolate incoming drone fire, allowing you to maximize the Batmobile's operational efficiency. Once the defensive grid collapses, detonating the explosive device clears the eastern sector of immediate hostile presence.

The Cauldron Sub-District Explosive

The final explosive device on Bleake Island is situated deep within the impoverished industrial sector known as The Cauldron. This device rests underneath the shadow of the massive shipping crane infrastructure, making it highly susceptible to multi-directional drone ambushes. The open layout of this specific arena demands constant movement to avoid getting surrounded by heavy tank units.

Prioritizing the elimination of mobile drone variants ensures you do not get overwhelmed by tracking lasers during the protracted download sequence. Utilizing the Batmobile's energy siphon can grant temporary shield boosts to withstand accidental direct impacts. After the final virus upload completes, a well-placed power winch pulse safely destroys the last remaining Bleake Island bomb threat.
