SEAF Artillery

S.E.A.F Artillery is a potential Optional Objective that can appear on Terminid, Automaton, and Illuminate controlled planets.

Objective Steps

• Activate Artillery Terminal
  • Helldivers must interact with the terminal to activate it. Before this step is completed, no shells can be loaded.
• Find artillery shells and load them into artillery gun
  • Helldivers must find artillery shells within the perimeter and load them into the artillery.
    • Interacting with shells will let Helldivers pick them up.
    • Shells must be transported and loaded into the loading area located at the artillery by hand.
• Use terminal to establish communication with Super Destroyer
  • Helldivers must interact with the terminal and use the directional inputs to establish communication with the Super Destroyer.
• Wait for the artillery system to initiate
  • Helldivers must wait the entire x seconds it takes to complete this step.
• Reward: 50 Experience, 200 Requisition Slips, and S.E.A.F. Artillery Stratagem.

Artillery Shell Type

7 shells will spawn around the site.

Tactical Information

• Outside discovering and reactivating a Radar Station, there are simple methods to discover the location of a SEAF Artillery site alongside one clear indicator telling if mission has one to begin with
  • During loadout selection, the SEAF Artillery is displayed as a standard issue stratagem if a SEAF Artillery site has been placed on the mission map. If this stratagem is missing, then the map does not have a SEAF Artillery site.
  • Attentive Helldivers can memorize the location of all hotzones shown during mission "Briefing" to narrow down location of undiscovered secondary objectives due these hotzones not being highlighted on the mission minimap. Usage of topographics confirm whether or not the secondary objective is a SEAF Artillery site or something else.
• Each SEAF Artillery site has five (5) to seven (7) shells. It is advised to generally not look for the possible surplus shells once the needed amount have been already transported near or into the loading chamber.
• The order and type of Artillery shell loaded is preserved when using the Artillery stratagem. Helldivers should consider which shells are of good use and remember in what order they were loaded.
  • The current shell to be fired will be displayed in the stratagem menu when calling it.
• SEAF Artillery can be used within the AoE of active Stratagem Jammers, Ion Storms, and when the mission timer reaches zero.
• SEAF Artillery shells behave similarly to their Eagle/Orbital counterparts.
  • High-Yield Explosive can destroy Detector Towers and Stratagem Jammers just like the Eagle 500kg Bomb and Orbital Precision Strike.
  • Mini-Nuke can destroy Gunship Facilities, Fuel Reserves, and Orbital Cannons just like the NUX-223 Hellbomb.

Trivia

• Before February 4th, 2025 (version patch 01.002.101), Helldivers were able treat the Artillery Shells like basketballs by repeatedly dropping and picking them up again to increase transportation speed thanks to small burst of sprinting between each drop-lifting.
  • There was also an even faster method where Helldivers "threw" the shells: This is done by dropping it while walking slightly forward of the shell picking it up again - but before the shell reached their hands they swapped to primary weapon. The shell couldn't stop at the hands because they were no longer free, so the shell did continue its trajectory.
    • Lore-wise the change from sluggish back-injury-inducing "kangaroo / deadlift"-carry-style and "heave"-push to now jog-enabling "wife-carry" and "log"-toss was explained in the patch-notes:

      The Ministry of Humanity has added a clause to its Principles of Correct Posture for Safe Lifting, now allowing Helldivers to jog while carrying two-handed items such as barrels and SEAF Artillery Rounds
