How to unlock co-op in Acecraft: Sky Hero is a common question for new players who want to team up with friends. The multiplayer mode is not available from the beginning, but once unlocked, it adds more strategy, teamwork, and rewards to the game. This guide explains the requirements, how to invite friends, preparation tips, and the benefits of playing co-op.
How to Unlock Co-Op in Acecraft: Sky Hero
Requirement: Clear Level 4-2
Multiplayer mode becomes available only after clearing Level 4-2. This stage is intentionally more challenging than Level 4-1 or 3-6, serving as the main checkpoint to unlock co-op. Once you complete it, a new Invite Co-op button will appear on the bottom right of the main screen.
Why Level 4-2 Is Harder
Level 4-2 introduces tougher enemy waves and more punishing patterns compared to earlier stages. The developers designed it as a skill test to ensure players have mastered basic mechanics before teaming up. Think of it as a gatekeeper stage that confirms you are ready for multiplayer runs.
How to Invite Friends in Multiplayer
Daily Invite Limitations
Inviting friends is limited each day. You can only send a certain number of invitations within 24 hours, after which the counter resets. This means you should plan carefully and save invites for the most challenging stages.
Friend List Management
Managing your friend list is essential. Add players with similar progression so they can actually support you. Remove inactive players using the trash bin icon, and exchange daily energy with active friends to gain additional resources. A well-curated friend list ensures smoother co-op runs.
Preparing for Co-Op Mode
Adjusting Transparency Settings
By default, your partner’s ship is set at only 14% transparency, making it nearly invisible. Adjust it to around 30–40% in the settings so you can track their position without cluttering the screen.
Choosing Pilots and Loadouts
Both players pick their pilots and loadouts at the start of a co-op session. Coordinate with your teammate to ensure you don’t bring identical builds. This variety makes your team much stronger overall.
Skill Path Coordination
Different skill paths complement each other. If one player focuses on damage output, the other can prioritize survivability or utility upgrades. This balance increases your chances of clearing difficult stages.
Benefits of Playing Co-Op
Double Damage & Wingmen
With two players, attacks and wingmen are doubled, boosting your firepower significantly.
Easier Boss Battles
Boss fights become much more manageable when both players focus fire and dodge together.
Higher Survival Chances
Even if one player struggles, the combined strength of two pilots increases the odds of survival and stage completion.
Best Tips for Co-Op in Acecraft: Sky Hero
Save Daily Invites for Hard Stages
Don’t waste invites on easy levels. Save them for bosses or missions that are tough to farm solo.
Farm Difficult Levels Together
Co-op helps cut down the time spent farming resource-heavy levels, making progress more efficient.
Don’t Worry If Teammates Disconnect
Even if your partner disconnects, their earlier contribution still helps. You can continue the run solo and reap the rewards.
Conclusion
How to unlock co-op in Acecraft: Sky Hero requires clearing Level 4-2, after which you can invite friends into multiplayer. By managing your friend list, adjusting settings, coordinating skills, and saving invites for tough stages, you can maximize the advantages of co-op. The mode not only doubles your strength but also makes boss battles and farming much easier, making it a must-try feature once unlocked.
