Completing the "Collision Course" quest in Arc Raiders requires a specific item that can be frustrating to hunt down if you aren't prepared. To satisfy Tian Wen’s request, you must locate, destroy, and retrieve a Comet Igniter from a fallen enemy.

While these explosive Arc entities can easily catch you off guard, mastering the combat loop required for this mission is straightforward once you understand their behavior.

How to Locate and Kill a Comet

Finding a Comet is relatively easy because they are common across most maps, but they are particularly abundant patrolling the beaches on the Riven Tides map. Visually, Comets resemble larger versions of Fireballs or Pops, similar in scale to a Surveyor.

You can identify them by the prominent blue light on their front. Be cautious: if that light turns yellow, the Comet has spotted you and is preparing to attack. To successfully complete Collision Course in Arc Raiders, keep these mechanics in mind:

  • Detection: A blue light means they are passive; a yellow light means they are hunting you.
  • Attack Pattern: Once aggressive, the Comet will roll directly toward your position before detonating.
  • The Window of Opportunity: You must destroy the Comet before it explodes to ensure the loot drops.

Efficiently Farming the Comet Igniter

If a Comet detonates before you kill it, you lose the chance at the quest item. The most effective way to complete Collision Course in Arc Raiders is to use high-damage, rapid-fire explosives that can stop them mid-roll.

The best tools for this job are:

  • Seeker Grenades: These are highly recommended because they track enemies automatically.
  • Snap Blasts: Excellent for dealing heavy burst damage quickly.

You can purchase these consumables from Apollo on a daily basis, making them a cost-effective way to hunt these targets. As long as the Comet hasn't spotted you, you can toss several Seekers from a distance to take it down safely.

Once the enemy is destroyed, a unique loot container will spawn. Unlike the standard ring-shaped containers found in the world, this one looks more like a core. Loot this specific container to find your Comet Igniter, stow it in a safe pocket, and return to Tian Wen to finish the mission.
