Planet Guardian — Player Guide

Your objective

Protect the glass dome while mining resources and improving the outpost. Version 0.0.6-dev.21 includes 36 materials, a mine reaching 2,000 m and 100 waves of flying enemies. The practical loop is to mine, return and store materials, refine supplies, improve equipment, then defend the base.

Language and controls

Choose System on the loading page to follow your device language, or select a language manually. You can change it later in Settings. Move and mine with WASD, arrow keys or the touch joystick. Use E to interact with the turret nearby, R for the refinery and G for the greenhouse near the facility. P or Esc pauses the game. Sound starts off; enable it with the Sound button.

A safer opening

Begin with a short mining trip and keep the route back open. The first wave arrives after 60 seconds, so do not assume your first research will finish before it. Return before the countdown ends and operate the main turret. Between attacks, choose a drill upgrade if mining feels slow, or begin charging a side turret if defence is the immediate problem.

Carry more and travel less

The starting backpack holds 24 units; the backpack upgrade raises this to 40. Returning to the base deposits carried materials automatically. Each block normally yields 3 units. Mining yield upgrades raise this to 4, 5 and 6 units per block; they do not replace drill speed upgrades. Check free space before breaking a valuable block.

Build a reliable route

One iron ingot and one copper ingot produce 3 elevator segments. Clear the rock, then drag a segment to the shaft or an existing elevator so it snaps into place. Each segment is square. Moving upward on the elevator is twice as fast. At deeper levels, craft and carry a return beacon to establish a return station near each 200 m interval. Travel takes 3 seconds and is unavailable during combat.

Choose a research path

The research lab has Living, Gathering and Base branches. Research costs no resources, but uses active play time. Only one research or side-turret charge can run at once. Leaving the lab keeps it running; pausing or closing the game stops progress. Refinery production has its own queue.

Recommended priorities

For early survival, prepare a useful main weapon and charge the first side turret. If repeated hauling is the bottleneck, upgrade the backpack and extend the elevator. Add mining yield after improving your carrying route; otherwise the extra output fills your backpack sooner. Reinforced glass reduces incoming dome damage by 20%.

Refining and repairs

Open a recipe branch to see its inputs, output and processing time. Production uses warehouse materials and deposits finished items there. Cancelling an unfinished production job returns its inputs. Keep repair supplies in reserve. Stone-to-iron extraction can fail: it has a 20% iron chance and guarantees iron on the fifth attempt after four misses.

Grow lettuce

Research the growing bed, transfer lettuce seeds from storage to the seed library, then sow a growth chamber. Each crop uses 1 seed and 2 water, grows for 60 seconds, and yields 3 food plus 1 seed when harvested manually. Greenhouse expansion adds a second chamber. A full warehouse prevents collection, so make room before harvesting.

Use food when it helps

Food grants 15% faster mining for 120 seconds; another serving refreshes the duration rather than stacking the bonus. There is currently no starvation penalty. If you have no seeds or active crops anywhere, the emergency seed recipe uses 5 soil and 2 water to make 1 seed in 20 seconds.

Aim and defend

The main turret fires automatically while you operate it. Aim with the arc or left and right controls, and press E to leave. The starting laser fires straight particles without homing. Charging Side turret I for 5 minutes activates the left launcher; charging II for another 5 minutes activates the right. Both cost no resources and fire homing missiles. Change weapons between attacks.

Handle the swarm

Enemies approach from several distant directions. Only enemies inside the current visible area can be targeted and damaged. Prioritize bomb carriers and broodmothers; use piercing fire against armour and suitable energy weapons against shields. Knockback buys time but cannot replace damage. The countdown pulses red during its final 30 seconds. Waves become harder, with bosses every 10 waves.

Defeat and optional revival

Defeat displays survival time.When available, the optional reward is one revival, full dome integrity and 30 seconds of invulnerability measured in active play time. Only a completed viewing grants it. Cancellation, failure or no ad gives no reward and deducts no resources. A later defeat may allow another request if the website has an eligible ad.
