Priceless Return

Priceless Return is a mining adventure in which you lead an expedition onto an uncharted planet after the starship runs low on energy and its journey home is put at risk. You gather resources and fend off mysterious creatures until you have enough energy to return.

Gather resources

Diamonds are a permanent resource used to upgrade weapons and core abilities. Gold is earned during each outing and can buy temporary firepower boosts. You can upgrade mining speed, hire more Diamond and Gold Miners, increase their movement speed and raise ore value.

You can withdraw from an outing before fighting to the end. Retreating in time protects your Diamonds and long-term progress, so each trip calls for careful timing. Once per match, you can call in an emergency full-screen clearance to turn the tide.

Upgrade your expedition

Three progression systems let you develop your weapons, mining operation and base. You can redistribute skill points at any time and try different strategies as you progress.

• Weapons: Mix and match Machine Guns, Electric Tower, Missiles, Lasers and Energy Ring. Increasing Machine Gun count and bullet ricochet can help clear monster swarms early on.
• Mining: Improve mining speed, hire more Diamond and Gold Miners, increase their movement speed and raise ore value.
• Base: Reinforce base HP, improve automatic HP recovery and add more supply skill uses.

Return home

Your final goal is to gather 25,000 Diamonds, research the ultimate weapon and restart the starship.
