Hardcore is an achievement that requires you to complete any mission in any campaign on brutal difficulty, with Onslaught Mode and Hardcore Friendly Fire Mode enabled.

Tips[]

  • This is currently the most difficult achievement in the game.
  • It is best to attempt this achievement with a squad of veteran players who all are comfortable with insane or brutal difficulty.
  • Attempting this achievement with 8 players in Reactive Drop is also not a bad idea.
