Launch Day Update (June 10, 2026)

The initial release of Into The Depths included the full base game with all core features. Players could explore procedurally generated caverns, build underground settlements, and manage resources in a single-player environment. This version introduced the Roguelite progression system, where each expedition into the depths resets your colony but unlocks permanent upgrades. The launch build also featured the first set of enemy types and elite enemies, which you can learn more about in our Enemy Types Guide and Elite Enemies Guide. No major bugs were reported at launch, but SmelJey immediately began working on quality-of-life improvements based on community feedback.

Hotfix 1.0.1 (June 12, 2026)

The first hotfix addressed critical stability issues. Players experienced occasional crashes when entering deep cavern zones, particularly during the transition between layers. This patch fixed those crashes and improved memory management for larger settlements. Additionally, SmelJey adjusted the spawn rates of certain resource nodes to ensure more balanced early-game progression. If you are struggling with resource gathering, our Resource Management Guide offers detailed strategies.

Hotfix 1.0.2 (June 15, 2026)

This update focused on balancing combat mechanics. The damage output of several elite enemies was reduced to prevent unfair one-hit kills on unprepared colonists. SmelJey also tweaked the cooldown of defensive structures, making them more reliable during wave-based attacks. A minor bug where save files could become corrupted after a crash was resolved.

Content Update 1.1.0 (June 20, 2026)

The first major content update introduced new gameplay features. SmelJey added three new unit types to the game, expanding tactical options for colony defense.

Balance Patch 1.1.1 (June 25, 2026)

Following player feedback on the Crystal Caverns, SmelJey rebalanced the resource yields from crystal deposits. The patch also reduced the health of certain mid-game enemies to keep difficulty curves consistent. A bug preventing colonists from pathfinding correctly around water tiles was fixed. This update also improved the UI for the upgrade system, which we cover in detail in our Upgrades Guide.

Hotfix 1.1.2 (June 28, 2026)

A critical hotfix resolved a save file issue that could cause progress loss after the game crashed during autosave. SmelJey also patched a visual glitch where certain textures would not load in the Cavern of Echoes. Minor performance optimizations were applied to reduce stuttering on lower-end PCs.

Content Update 1.2.0 (July 5, 2026)

The second major content update introduced the first prestige system iteration. Players can now reset their colony for permanent bonuses, a key feature for Roguelite fans. This patch also added new events and challenges, which you can explore in our Challenges Guide and Event Guide. A new boss enemy, the Deep Wyrm, was added to the final cavern layer. For strategies on defeating it, see our Boss Guide. Quality-of-life improvements included faster crafting times and a reworked inventory system.

Balance Patch 1.2.1 (July 10, 2026)

SmelJey adjusted the Deep Wyrm's attack patterns to make the fight more fair after reports of unavoidable damage. The prestige system was also tweaked to grant slightly more bonus resources per reset. A bug where certain items could not be crafted after prestige was fixed.

Hotfix 1.2.2 (July 12, 2026)

This hotfix addressed a memory leak that occurred when players spent extended time in the Crystal Caverns. The developer also fixed a localization issue where some tooltips displayed incorrect text in non-English languages. Performance in late-game colonies was improved by optimizing particle effects.

Content Update 1.3.0 (July 20, 2026)

The third content update brought the first collaboration event, introducing crossover content from another indie title. This event added limited-time enemies and rewards. SmelJey also expanded the lore with new story entries found in the deepest caverns. For lore details, check our Lore Explained Guide.
