Blood & Lineage supports 1 to 4-player LAN co-op, letting you team up with friends to battle through Greek mythology's greatest challenges together.
Blood & Lineage uses LAN connectivity for its co-op mode, supporting up to four players. This means all players need to be on the same local network to play together. Ensure your firewall settings allow the game's network traffic if you experience connection issues.
To start a co-op session, one player hosts a game and others on the same LAN can join. Make sure all players have updated to the same game version to avoid compatibility problems.

With four unique demigod classes available, a full co-op squad can field one of each class for maximum coverage. Each class brings a distinct toolkit designed for strategic teamwork, so diversity in class selection generally produces the strongest teams.
That said, duplicate classes are not a problem if players build and gear their characters differently. Two players on the same class can specialize in different roles through their stat optimization and loot choices.

Effective co-op play in a Musou game requires awareness of where your teammates are and what they are doing. In massive horde fights, spreading out to cover more ground is often better than clustering together.
During boss encounters, the strategy flips — you want coordinated focus rather than spread coverage. Designate roles before engaging bosses and communicate during phase transitions to avoid wasting powerful cooldowns.

Many roguelike co-op games scale enemy count or health based on the number of players. Expect Blood & Lineage to become more intense with a full squad, though having four players generally makes the game easier overall due to the combined firepower and ability to revive each other.
If your group finds co-op too easy, increase the difficulty setting. The game features adjustable difficulty levels, and higher tiers offer better loot and greater challenges that truly test team coordination.
