Progress depends on gathering more than 70 unique items, customizing weapons from over 5,000 possible combinations, and defeating a roster of ten‑plus bosses.

01 / THE GUIDE
Exploration and Biomes
The planet’s surface is divided into multiple biomes, and each biome presents specific hazards that must be navigated to reach deeper areas. Moving between biomes is required to uncover the planet’s hidden mysteries.
Because biomes are separate zones, players need to adjust their approach as environmental challenges shift. Recognising each biome’s layout helps plan item usage and weapon upgrades.
- Observe hazard patterns before entering a new biome.
- Sketch a quick map to avoid unnecessary backtracking.

Item Collection and Uses
Over 70 items are scattered throughout the planet, and each item has a distinct purpose. Collecting items is necessary to progress deeper into the environment and to boost combat capability.
Items can be used on their own or combined with weapons, offering strategic options for dealing with enemies and environmental obstacles. The variety encourages experimentation with different pairings.
- Prioritise items that address the current biome’s hazards.
- Balance offensive and utility items for flexibility.

Weapon Customization
Weapons can be customised using the collected items, allowing for more than 5,000 possible combinations. Customisation centres on finding powerful combinations between weapons and items.
Players experiment with different configurations to find setups that work best against specific enemies or bosses. The system rewards creative pairings that exploit item effects.
- Test combinations in low‑risk areas before major boss encounters.
- Record successful setups for quick reference in future runs.

Boss Battles
The game features more than ten bosses, each presenting a unique challenge that tests the player’s weapon setup and item strategy. Boss encounters appear at key progression points.
Defeating a boss often requires adapting your loadout to the boss’s specific attack patterns, making preparation and flexibility crucial for success.
- Study a boss’s pattern on the first attempt to adjust your loadout.
- Reserve high‑damage items for the final phase of a boss fight.

These changes create varied experiences, encouraging replayability by forcing players to adapt to altered conditions each time they start a new run.
