Hollow Survivors: Prologue

Hollow Survivors: Prologue is a free standalone preview for the full game, Hollow Survivors. The store description is explicit: "The prologue is only part of the full game and is completely free." The full game launched on April 10, 2025, as announced in the developer's news posts on April 8 and April 10, 2025. Since the full game's launch, the developer has continued updating the prologue — on July 26, 2025, they added 30 new card upgrades ported from the full game, along with new dialogue and balance changes. The developer's note in that post ("it's been a long time since I updated the prologue version") suggests updates are periodic rather than continuous, but the July 2025 post is the most recent developer communication available, and it shows active engagement with the prologue as a gateway to the full product. As of today (September 24, 2026), the last developer communication for this app was on July 26, 2025 — approximately 14 months ago. There is no established regular cadence for prologue updates (only one major content post and one feature patch in the entire history), so it is difficult to conclude that silence signals anything beyond irregular maintenance. Critically, the prologue's nature as a permanent free preview tied to an actively sold full game means it does not have a conventional "completion" state — the developer has neither announced it is finalized nor that further backports are planned. Given the prologue's design as an ongoing advertisement for the full game, this app is best understood as continuing to serve that function.
