Zombie's Retreat 2 v1.1.0 Released

By MaC

Zombie’s Retreat 2: Gridlocked has pushed out version 1.1.0, the latest update to Siren’s long-running 2DCG survival RPG. The thread has racked up over 7.5 million views and more than 1,200 likes on F95zone, making it one of the most closely watched sandbox titles in the dystopian/horror space right now.

The sequel picks up Siren’s original zombie-corruption premise and expands it into a full RPG framework, layering turn-based combat, puzzle-solving, and sandbox exploration on top of the series’ signature harem and corruption content. Gridlocked’s setting drops players into a quarantined, monster-infested world where survival and seduction routes intertwine — a mix of internal-view CG work, group content, and the incest and voyeurism threads the series is known for.

Version 1.1.0 arrives alongside continued platform support for both Windows and Android, keeping the game accessible to Siren’s mobile-leaning audience. As with prior updates, the changelog is gated behind a spoiler tag on the official thread, so players chasing specific route or character progress will want to check the patch notes directly before diving back in.

With views climbing past 7.5 million, Gridlocked remains one of Siren’s flagship projects, and v1.1.0 signals continued active development rather than a wind-down.
