Revision 1

Overview

The Exploit system is a unique combat mechanic in The Expanse: Osiris Reborn that ties together environmental awareness, tactical positioning, and companion abilities into a single powerful action. Rather than simply shooting enemies directly, players can identify interactive environmental areas, maneuver enemy groups into position near those areas, and then command their companions to execute specialized attacks that leverage the environment itself. When executed successfully, an Exploit can eliminate an entire group of enemies in a single action, making it one of the most impactful tools in the player's tactical arsenal.

The system encourages players to constantly scan their surroundings for opportunities rather than relying purely on direct firepower. Every encounter space is designed with environmental elements that can be exploited, but matching the right companion to the right opportunity is the key to success.

How Exploits Work

Using an Exploit follows a three-step process that requires both awareness and timing:

• Identify the opportunity: The player must spot an interactive environmental area in the combat zone. These can include unstable structures, exposed electrical systems, fuel containers, loose overhead fixtures, and other hazards scattered throughout the level geometry.

• Position enemy groups: Once the environmental opportunity is identified, the player needs to maneuver enemies into the area of effect. This can be done through aggressive flanking to push enemies back, using grenades to flush them from cover, or drawing their attention so they cluster near the hazard.

• Command the companion: With enemies in position, the player orders a companion to execute their Exploit ability on the environmental element. The companion carries out a specialized attack based on their Exploit category, triggering the environmental hazard and dealing massive damage to all enemies in the area.

The result is often devastating. A well-executed Exploit can clear out an entire squad of enemies that might otherwise require a prolonged firefight. However, using the wrong companion category on an environmental element will not produce the desired effect, so players must pay attention to which category matches each situation.

Exploit Categories

Each companion in the game has one of four Exploit categories. These categories determine what kind of environmental interactions the companion can trigger. The four categories and their associated companions are:

Precision

Precision Exploits focus on identifying and targeting structural weak points in the environment. When a Precision companion is ordered to act on a vulnerable element, they deliver a carefully aimed attack that triggers a chain reaction. This might cause overhead fixtures to collapse onto enemies below, destabilize catwalks and platforms so they give way, or trigger stored hazardous materials that were held in check by a single support point. The key characteristic of Precision is accuracy: the companion targets the exact point that will cause the most environmental damage.

The companions with the Precision category are J and Regina. Having either of them in the squad ensures access to Precision Exploits, which are particularly effective in environments with overhead structures, scaffolding, or precariously balanced objects.

Demolition

Demolition Exploits take a more direct approach. Rather than targeting a specific weak point, Demolition companions destroy cover and terrain outright. When enemies are hunkered behind solid barriers, a Demolition Exploit can obliterate those barriers entirely, leaving enemies exposed and vulnerable to follow-up fire. This category is especially useful against heavily entrenched enemy positions where conventional weapons cannot penetrate their cover.

The companions with the Demolition category are Polly and Michael. Demolition Exploits shine in encounters where enemies use fortified positions with destructible cover elements.

Malfunction

Malfunction Exploits target electrical systems and electronic infrastructure. When a Malfunction companion activates their ability on an electrical element, they wreck and disable it in a way that damages nearby enemies. This can cause power conduits to overload and arc electricity into anyone standing close, computer terminals to explode, or enemy equipment to short-circuit and become useless. The distinction between Malfunction and Cyber-attack is important: Malfunction destroys the system, while Cyber-attack repurposes it.

The companions with the Malfunction category are Teo and Zafar. Malfunction Exploits are common in space station interiors and industrial areas where electrical infrastructure is everywhere.

Cyber-attack

Cyber-attack is the rarest Exploit category, held by only a single companion. Instead of destroying electrical systems, a Cyber-attack Exploit turns them against the enemies. This means automated turrets can be hacked to fire on their own allies, security doors can be sealed to trap enemies in kill zones, and environmental control systems can be weaponized to flood areas with harmful atmospheres or extreme temperatures. The creative potential of Cyber-attack is enormous, but its availability is limited to a single squad member.

The only companion with the Cyber-attack category is Aleesha. Because she is the sole source of Cyber-attack Exploits, including her in the squad unlocks tactical options that are simply unavailable otherwise. Players who want access to the full range of Exploit possibilities should consider building their squad around Aleesha for missions in electronically dense environments.

Tactical Considerations

Squad composition is critical for getting the most out of the Exploit system. Since the player brings two companions on each mission, the combination of Exploit categories in the squad determines which environmental opportunities can be leveraged. Having two companions with different Exploit categories provides the broadest tactical flexibility, ensuring that the squad can respond to multiple types of environmental elements in any given encounter.

For example, pairing a Precision companion with a Malfunction companion means the squad can handle both structural hazards and electrical systems. Pairing a Demolition companion with a Cyber-attack companion covers both destroying enemy cover and turning automated systems against foes. Players should assess the likely environment of upcoming missions and select companions whose categories match the expected opportunities.

It is also worth noting that Exploit opportunities are not always obvious at first glance. Players who invest time in scanning each combat area before engaging will often discover hidden environmental elements that can turn an otherwise difficult fight into a decisive victory. The tactical visor and general environmental awareness are just as important as raw firepower when it comes to mastering the Exploit system.

The Exploit system rewards preparation and observation. Players who rush into combat without checking their surroundings will miss opportunities that could end fights in seconds. Those who take the time to identify environmental elements, choose the right companions, and position enemies carefully will find that Exploits are among the most satisfying and efficient tools in the game.
