Each specialization comes with a distinct base appearance and transformation effects. Available choices depend on your research progress.

More Relics and More Build Possibilities

New relics introduce additional ways to combine weapons, mining, defense, resource management, and active abilities.

September additions include relics that reward collecting different relic types, repeat eligible effects, amplify relic bonuses, add projectiles, strengthen close-range attacks, reward damage-free waves, and provide extra supply choices.

Further additions introduce:

Relic icons, descriptions, current-bonus displays, activation effects, and active-skill buttons have also received extensive improvements.

Continue Your Exploration

Local exploration recovery saves progress at the beginning of each wave.

After an interruption, use Continue Previous Exploration from the main menu to restart from the saved wave’s beginning, retaining your weapons, relics, resources, base health, and wave statistics.

Starting a new exploration warns you before replacing unfinished progress. Recovery data also includes integrity checks and backup fallback.

Fixes and Stability

This month also addresses interrupted landing sequences, returning from the background, opening weapon supplies after re-entering a planet, waves failing to advance after supply selection, missile hit detection, lingering poison clouds, duplicate settlements, missing rewards, and various interface issues.

Additional Development Progress

Additional relic batches have been implemented in the project, covering temporary relic cloning, wave rewind, shared ammunition, continuous-fire bonuses, delayed bombs, upgrade-based bonuses, relic sacrifice and revival, base movement, upgrade credit, supply borrowing, run-specific relic bans, and cooldown resets.

These additions are tracked separately from the versioned release notes; their availability in a downloadable build has not yet been confirmed.

Thank you for playing and sharing your feedback. Your battle reports and build experiments continue to help improve Outpost 4!
