Mental Omega Wiki

The Mercury Strike is a support power available for the United States through the Mercury Network Uplink. It, as its name suggests, fires a laser beam from one of the Mercury satellites in space that is particularly effective against infantry and light vehicles, though less so against heavier targets.

An interesting matter to note is that Athena Cannons benefit from the Mercury Strike; if one is used near them, the Athena Cannons can perform stronger attacks for a period of time as the Mercury Strike requires the Mercury satellite to recalibrate its position, allowing the Athena Cannons to communicate with it faster.

AI behavior

AI's Mercury Strike always targets the player's largest group of units, while ignoring invisible units. In addition, AI units affected by this support power will immediately target the Mercury Network Uplink.


It seems its destructive power has greatly diminished since the strike on the Eiffel Tower. Both our enemies and us have overestimated the long-term capabilities of the satellite.

Act One

  • In Recharger, after Volkov charges up the Eiffel Tower and uses it to destroy the nearby European outpost, the Eiffel Tower will be destroyed by an abnormally strong Mercury Strike, forcing Volkov to complete the rest of his mission in the conventional way.
  • In Idle Gossip, the Allies will use the Mercury Strike again, but outside the battlefield.
  • In Death From Above, the Allies will use the Mercury Strike against the invading Latin Confederation forces. The Latin Confederation's success in this mission renders the Mercury Strike unusable for the rest of Act One and some of Act Two.

Act Two

  • The Mercury Strike becomes usable by the player in Ghost Hunt.
  • In Reality Check, Mercury Strikes are used during the final boss battle when Norio is at 20% health. Unlike regular Mercury Strikes, the attack frequency becomes shorter as the battle progresses. The frequency ranges from 20 seconds to as little as 3 seconds per strike.


  • Due to the Allies lost the Mercury Satellite connection after failing the Antarctic battle, Mercury Strike has been locked in The Remnant.

Special Ops

  • In Convergence, Mercury Strike can be used during the battle at sides of the canal, if Tanya is chosen to fight.
