“A backpack-mounted Hellbomb that can be armed by the wearer or an ally, starting a countdown. Users are recommended to remove the backpack before the countdown reaches zero.
— Ship Management Terminal
The Portable Hellbomb is a backpack Stratagem that grants the player the utility of an at-demand Hellbomb free from the restriction of only being usable near mission objectives.

Functionality
By default, the Portable Hellbomb is in an inert state, providing no benefits while inactive and occupying the backpack slot of the player when carried. In order to utilize it, the Portable Hellbomb must first be activated, either by the bomb carrier or a teammate standing close to the wearer. The wearer can activate it by pressing the "Use Backpack Function" button (PC default press 5, PlayStation default press D-Pad Down), while another player close by can interact with the backpack with the "Portable Hellbomb" prompt (PC default press E, PlayStation default press X).
Upon activation, the Portable Hellbomb will emit a loud alarm and begin counting down. After ten seconds (10 seconds), it will explode, regardless of whether or not it is being worn. There is no way to suspend or cancel the countdown, and no way to detonate the explosive payload early.
Tactical Information
- True to its name, the Portable Hellbomb is an explosive payload that allows the player to deploy a Hellbomb explosion at any location that they can reach.
- The Portable Hellbomb has the same destructive capabilities as the standard Hellbomb, meaning that it can instantly kill all enemies within 17-25 meters of the epicenter and destroy any structures that a standard Hellbomb can.
- Because it is backpack-carried, the Portable Hellbomb can only be dropped in locations where the player can physically reach while wearing it.
- While calling in a standard Hellbomb has a significantly lower cooldown and does not cost a Stratagem slot, Hellbombs can only be used on top of mission objectives like Rogue Research Stations and Gunship Facilities, and take additional time to protect and arm. The Portable Hellbomb can be carried to and deployed in any location that its wearer desires, being activated with a single input that cannot be interrupted.
- Unlike the standard Hellbomb, the portable Hellbomb cannot be prematurely detonated by getting shot once armed, making it much safer to use.
- Because of its mobile on-demand nature, the Portable Hellbomb can be considered a general-purpose explosive that can be used to deal with whatever situation arises.
- Because of its wide destructive radius, it can be used to kill a large number of enemies in a general area, provided the player can reach the middle of the group. Due to its immense destructive power, any and all enemies close to the center of the explosion will be instantly killed, even large enemies like Factory Striders or Bile Titans.
- The other general use for the Portable Hellbomb is to destroy objective structures without having to call down and activate a standard Hellbomb. This is most useful to either save time such as when the target is a Gunship Facility or Monolith, or a situation when a Hellbomb cannot be called down such as underneath an active Stratagem Jammer or destroying an objective during an Ion Storm.
- In a pinch, the Portable Hellbomb can be used to significantly weaken an enemy reinforcement wave or kill a significant amount of a pursuing enemy force when retreating. For instance, if a Bot Drop has been called in, activating the Portable Hellbomb directly underneath the flare as Dropships begin disembarking their passengers can kill most if not all of them, while dropping an active Portable Hellbomb while running away from a large Bug Breach will buy a significant amount of time and space to escape.
- Be very mindful of the Stratagem's long cooldown, and deploy it sparingly.
- Even with all Ship Modules unlocked, a Portable Hellbomb can only be called down roughly once every four minutes. Try to use it only on important objectives where a standard Hellbomb may be difficult to deploy, or when a significant amount of enemies can be killed.
- However, if the currently-equipped Portable Hellbomb has not been used and the Stratagem is coming off of cooldown soon, it can be beneficial to search out an opportunity to deploy it and then call down a fresh one. While keeping the Portable Hellbomb in reserve for optimal situations can offer the most benefit, not using the bomb at all wastes its potential.
- If a safe and readily accessible location can be reached (such as the Extraction point or a safe spot near the middle of the map), calling down a Portable Hellbomb can be helpful, even if still equipped with an unexploded one. This puts an additional Portable Hellbomb on the field ready to be retrieved and used while allowing the Stratagem to come off of cooldown to deploy another one.
- Due to the immense destructive power of the Portable Hellbomb, as well as the fact that it is worn on the player's back, surviving its explosion is generally considered optional but encouraged.
- Optimal use of the backpack is to reach the target area, activate the bomb, drop it onto the ground and then run at least 30 meters away.
- Marking the Portable Hellbomb on the ground can display its distance on the HUD while running away, as well as marking it for teammates to see and thus notify them that an explosion is imminent.
- Be sure to refill the stamina bar as much as possible prior to activating and dropping the Portable Hellbomb. Otherwise, consuming a Stim upon dropping the explosive will temporarily grant infinite stamina as well as healing all incoming damage during the retreat sprint. The Experimental Infusion booster increases sprint speed and damage resistance to help improve chances of survival.
- Diving to the ground (going prone) near a Hellbomb explosion reduces incoming explosive damage by 90%, significantly increasing the chance of survival within the outer radius (25m) and reducing the likelihood of being ragdolled by the shockwave (45m).
- Activating the bomb and then running towards the target area will grant the player the ability to precisely control the location of the detonation, as well as achieve faster results due to activating the countdown earlier, at the cost of a Reinforcement.
- Wearing armor with the Democracy Protects passive will grant a 50% chance to survive the explosion even if the backpack is still being worn. However, the massive push force imparted by the explosion can still throw the player into nearby level geometry, killing them from the force of the impact.
- Optimal use of the backpack is to reach the target area, activate the bomb, drop it onto the ground and then run at least 30 meters away.
- The Hellbomb backpack can also be armed by teammates.
- Attempting to stim or resupply a Helldiver wearing the backpack will instead activate the Hellbomb (this does not apply when using the Stim Pistol).
Trivia
- In combination with an Anti-Tank Emplacement, the Portable Hellbomb can be activated and placed behind the incoming beam, causing it to be catapulted when the Stratagem unfolds.
- During extraction, the Hellbomb can be armed and carried onto the Pelican, resulting in a breathtaking detonation during flight. The explosion is non-lethal to Helldivers on board.
