Communication is key in co-op. Designate roles: one player can focus on crowd control while the other targets specific threats. Share ammunition and healing items, especially if one player is struggling. Utilize partner actions like 'cover fire' or 'revive' effectively. When one player is grabbed, the other should quickly intervene. Coordinate on puzzles and boss weak points. Remember that your partner can revive you, so don't be afraid to take risks if you know they can back you up. A well-coordinated team is far more effective than two lone wolves.
