The free cooperative zombie survival shooter No More Room in Hell received a major update announced on Steam on September 1st, bringing the Source Engine classic up to modern standards with 64-bit support, a Vulkan renderer, and Steam Networking. The update was reported by GamingOnLinux on September 9th.

No More Room in Hell is a free cooperative first-person survival horror modification for the Source Engine, inspired by George Romero's "Of the Dead" film series. It won PC Gamer's Mod of the Year 2011 and ModDB's Editor Choice Multiplayer Mod of the Year 2011. The game is set during a collapse of civilization from a disease of unknown origin, in which the dead rise and spread the infection through their kills.

The update adds 64-bit binaries that launch automatically on systems running a 64-bit operating system, plus a borderless window option in video settings and UI scaling for high-resolution screens. The Source Engine upgrade also pulls in bicubic lightmaps and radial fog from the Half-Life 2: 20th Anniversary Update.

For Linux players specifically, the new Vulkan renderer is enabled by default. Steam Networking support means port forwarding is no longer required to host or join multiplayer sessions.

The patch also fixes several technical issues. It addresses a prediction bug where a player moved on the client had their input-based movement for that tick ignored in non-player actions, and an issue where variables such as position would not update correctly to match the server in certain situations. Breakable props that were not gibbing correctly are fixed, as is a case where the player hull was mis-predicted and caused rollback.

The update is the latest sign of life for a game that has remained free on Steam since its release. The developers have not detailed what comes next beyond this modernization pass, and no further roadmap has been announced.

Why it matters

A 2011-era free Source Engine mod gets a modern technical overhaul that keeps it playable on current hardware and Linux systems.
