About this game
Kingmoon is an open-world 3D action game. King Regulus rules the stars from his moon, and kingdoms of robots and aliens occupy every planet. You start with a small ship and a flag.
You fly free, with no loading screen between sky and ground, over planets divided into 24 sectors. Land, step out of the ship, tear down the enemy flag and hold yours to turn the sector to your side. Every enemy sector has an aerial Guardian: defeat it and the guide light shows where to plant the flag.
The campaign has 25 missions in 5 systems: Torum, Glacia, Pyra, Sair and Nucleon. Each world has its own climate and rules, and each system ends with a boss, from the Tick Colossus to the Mother Core station. After the five bosses, the road leads to the King's Moon.
Between missions, you earn crystals for the Hangar: 4 heroes, 4 ships, 4 weapons, the mech and the ship parts, which change its look. The game has contracts, badges, a daily chest and an empire that grows with every planet you conquer. The lines are voiced in English, with subtitles in Portuguese, English, Spanish, Hindi, Japanese and Arabic.
How to play
- Fly through the planet's atmosphere: the keyboard flies the ship and the mouse aims.
- Head to a sector and land near the enemy flag. Step out of the ship and tear the flag down.
- If there is an aerial Guardian, get back in the ship and defeat it. It drops a guide light on the ground.
- Clear out the defenders and hold the plant button until the flag rises. The sector joins your kingdom.
- Keep an eye on the radar: when one of your flags is attacked, arrive on nitro before it falls.
- Conquer the sectors the mission asks for and, at the end of each system, beat the boss to move on.

Tips
- Fly close to the ground: the low pass fills the nitro. The tank lasts about 4 seconds, so use it in bursts.
- Space with a direction performs a maneuver. Dodging a shot at the last moment refills a little nitro.
- Crashing into buildings and rocks at high speed damages the hull. If the hull hits zero, the ship is disabled for 6 seconds and comes back on its own.
- Hold F for 3 seconds to plant, and only plant when the ground is clear: defenders nearby get in the way.
- When the alert shows one of your flags under attack, the siege timer always leaves enough time to arrive on nitro. Follow the arrow at the edge of the screen.
- Near one of your flags, hold F to set up the garrison: shield, turret or drone, bought with Cores from the vault.
- Every Guardian fights in its own way. The one that bombs only hits you if you pass underneath, and the shielded one falls from behind.
- Call the mech when the fight gets heavy, but remember: it only charges by taking down enemies.
