Developer Hunter Studio has revealed that its hit beat ‘em up rogue-lite Lost Castle 2 will exit Steam Early Access and launch its full 1.0 version on June 11, 2026. To celebrate this, the game will be available for 20% off from April 9 to April 16 during the Triple-i Steam Sale.
The announcement was accompanied by a brand-new gameplay trailer showcasing the chaotic co-op combat, the exotic new environments, and epic boss fights that await when the full game drops. The trailer debuted at the recent Triple-i Initiative Showcase.
