Tactical Information

  • The Orbital Walking Barrage hits the target point with a salvo of explosive shells, and then follows up with several additional salvos that "march" forward.
    • The shells fired by this Stratagem are the same as those used for Orbital Precision Strike, Orbital 380mm HE Barrage and SEAF Artillery's Explosive shells, making them among the strongest explosive ordnance that can be deployed.
    • A total of fifteen shells are fired by this Stratagem, in five three-shell salvos; with the More Guns Super Destroyer upgrade, six salvos are fired for a total of eighteen shells. Each shell in a salvo is separated by an interval of one second, followed by a three-second pause before the next salvo. Total barrage time is 27 seconds (32 seconds when upgraded).
    • Each salvo is separated by an interval of approximately 25 meters, meaning that the final salvo will land approximately 100 meters away from the first salvo (125 meters away when upgraded).
    • The marching direction of the Walking Barrage is the same as the throwing direction of the Stratagem ball. This means that the first salvo lands on the approximate location of the Stratagem ball, and then moves away from the player's original position.
  • The primary advantage of the Orbital Walking Barrage is that it moves forward, covering a large amount of terrain.
    • After the first two salvos, it is safe for players to move forward to the location of the impact point of the first salvo, to finish off any stragglers, engage enemies being bombarded by subsequent barrages, or to claim objectives. In particular, this allows players to actively move forward after 10-15 seconds instead of waiting for the full 27 seconds before they can act.
    • The wide area coverage of the barrage is useful for reaching faraway targets, as well as to inflict damage over a large enemy base, such as a Terminid Mega Nest or Automaton Fortress on the Super Helldive difficulty.
    • Beware that the Stratagem ball and beacon will remain at its original location for the duration of the barrage. So while it will keep track of the total duration of the barrage, it will not mark the location where the shells are falling.
  • The forward-moving nature of the Orbital Walking Barrage makes it a poor choice for defending ground, as the first two salvos may land on target but the subsequent salvos will land behind any approaching enemies. As such, it is not reliable for dealing with Bug Breaches and the like.
  • Be very judicious about when to deploy this Stratagem, as it has a very long cooldown. Try to reserve it for extremely tough enemy bases, or for reaching faraway enemy objective structures that are out of the way to save time.
