GSC Game World officially announced the first expansion for Stalker 2: Heart of Chernobyl during Microsoft's Xbox Partner Preview showcase. The expansion, titled "Cost of Hope", returns players to the power plant that served as the cornerstone location for the original S.T.A.L.K.E.R. titles.
The reveal trailer shown at the showcase revisits the industrial, irradiated interiors and familiar, claustrophobic corridors of the plant, while teasing fresh missions, new adversaries and additional gear for players to discover. The developer had teased an announcement ahead of the event, but an expansion was not widely expected.
Specific release timing and platform details were not confirmed at the showcase. GSC Game World provided only the initial trailer and a brief overview of the setting, leaving finer details such as release date, pricing and platform availability for a future update.
The announcement marks the first major post-launch expansion for Stalker 2: Heart of Chernobyl since the game's release, and signals continued support and content updates from GSC Game World.
