(Additional information: Latest update as of July 27.)

Release Date: August 21, 2026

Season 10 marks one of the biggest updates in Hero Siege’s history, introducing a brand-new act, a complete progression overhaul, major performance improvements, expanded endgame progression, and several premium features becoming free for all players.

New Act IX: Ebontharn

Season 10 introduces Act IX: Ebontharn, which becomes available after defeating Odin.

In a major shift, the developers announced that future story content will no longer be paywalled. Act IX is included free as part of the base game, allowing every player to experience the new campaign without purchasing an expansion.

The update also adds three challenging new Uber Bosses:

Progression System Overhaul

The game’s leveling experience has been completely redesigned.

Key changes include:

Nightmare difficulty has been removed.

Players now progress from Level 1 to 100 during their first Normal playthrough.

Completing Normal unlocks the new default Nightmare world, followed by the newly introduced Hard difficulty before Inferno.

Numerous side zones have been added throughout every act to create a longer, smoother progression experience, with Act IX serving as the finale of the Level 1–100 journey.

Several questlines have also been streamlined to reduce unnecessary backtracking and improve overall game flow.
