The right crew combination can make or break a run in Cobalt Core. Here’s a breakdown of the strongest synergies and how to play them.

Top Tier Combos

The Shield Fortress

Crew: Engineer + Medic

This combo focuses on survivability. The Engineer generates extra shields while the Medic heals chip damage. You’ll rarely die, but runs take longer.

The Glass Cannon

Crew: Gunner + Pilot

Maximum damage output. The Gunner’s high-damage cards pair perfectly with the Pilot’s repositioning abilities. You’ll kill things fast but need to dodge well.

The Card Engine

Crew: Hacker + Scientist

Draw and manipulate your deck aggressively. This combo cycles through cards rapidly, letting you play your best cards more often.

How Synergies Work

Each crew member adds cards to your deck. When two crew members’ cards interact well — like the Pilot moving you into position for the Gunner’s aimed shot — that’s a synergy.

Pro tip: Look for cards that say “if you moved this turn” or “if you have shields.” These are synergy enablers.
