Status: Confirmed. GSC Game World is releasing Update 2.0 and the Cost of Hope expansion for S.T.A.L.K.E.R. 2: Heart of Chornobyl on August 20, 2026, with both arriving at the same moment on every platform. The update is free for anyone who owns the game; Cost of Hope is a paid expansion.
Quick answer: Update 2.0 and Cost of Hope go live at 1PM UTC on August 20, 2026 (6AM PDT / 9AM EDT) across PC, PlayStation 5, and Xbox Series X|S.
Release time: August 20, 2026 at 1:00 PM UTC
Cost of Hope release time by time zone
There is no staggered rollout. The same unlock applies to all three platforms, so the only difference is what the clock says where you live.

| Pacific (PDT) | 6:00 AM |
| Central (CDT) | 8:00 AM |
| Eastern (EDT) | 9:00 AM |

What you need to own to play Cost of Hope
Cost of Hope requires the base game. S.T.A.L.K.E.R. 2: Heart of Chornobyl left Game Pass in November of last year, so a subscription no longer covers it and you will need to buy a copy.
Owners of the Ultimate Edition already have the expansion. That version bundles a season pass covering two major story expansions, and Cost of Hope is the first of them, so it unlocks automatically at launch with no extra purchase. Everyone else can buy the expansion on its own or upgrade to the Ultimate Edition. On Xbox, the expansion is covered by Xbox Play Anywhere, meaning a single purchase carries across supported Microsoft platforms.
Update 2.0: Free for all owners
Update 2.0 is the larger technical change of the two. It moves S.T.A.L.K.E.R. 2 onto a newer version of Unreal Engine 5 and adds new content and improvements on top of that engine jump. GSC has framed it as a stability and visual overhaul, and it costs nothing for existing owners.
Importantly, 2.0’s changes are not gated behind the paid expansion. Whether you load the original campaign or start Cost of Hope, the update’s features are active from the first launch after installing it.
Note: a full patch list has not been published, so expect specifics to land alongside the release itself.
What Cost of Hope adds to the Zone
You play as Skif again, and the expansion’s story runs parallel to the main campaign rather than after it. A mysterious PDA signal pulls him into a separate chain of events, which is how the new content threads itself into a normal playthrough.
The plot centers on the collapse of the D4 Treaty, the fragile agreement holding Duty and Freedom together. Duty still treats the Zone as a threat that must be destroyed; Freedom sees the anomalies as something humanity should learn to use. You pick a side, and that choice shapes how the conflict resolves.
| Addition | Details |
|---|---|
| New regions | Iron Forest and the Chornobyl Nuclear Power Plant, each with its own points of interest and hidden areas |
| Length | Dozens of hours of nonlinear content |
| Gear | New weapons and equipment found across the new locations |
| Enemies | New anomalies and deadlier mutant encounters |
| Quests | New main story missions plus side content |
| Place in the saga | Middle chapter of the second trilogy, with a further expansion to close the arc |
How to start Cost of Hope and confirm it installed
Both releases land on the same clock across PC, PS5, and Xbox Series X|S, and GSC has not signalled any change to that window. If the timing shifts, it will be announced through the studio’s official channels.
