  • Because you only receive one mine, use it wisely.
  • If you're planning to use it in motion-sensor mode, place it where the enemies will most likely pass by.
    • Alternatively, place it facing the C4 in Original. Its extreme range and damage will entirely prevent people from defusing, or safely destroying it.
  • Keep your distance from it after planting, or stay behind it. It can easily kill you.
  • You can take the advantage of its extremely high knockback power to jump higher than OICW and reach hard spots, but it carries a near-suicidal risk. You will die without a Titan Doll in Scenario (this has been fixed in later updates).
  • If the enemy grenade explode nearby the mine (including Zombie Grenade), the mine will forced detonation.

Zombie Scenario

  • It doesn't affect barriers at all.
  • It can deal damage on bosses, ranging from 30k-40k per mine depending on how close it is placed around the boss.
