Time to give No More Room in Hell another spin? This classic free first person survival horror just levelled up with a major upgrade.

Not played it before? Here's the official blurb from Steam: "A tribute to the highly acclaimed film series in which the above quote originated from, No More Room in Hell (PC Gamer's Mod of the Year 2011, ModDB's Editor Choice Multiplayer Mod of the Year 2011), is a co-operative realistic first person survival horror modification for the Source Engine. Taking inspiration from George Romero's "Of the Dead" series, the mod is set during a time in which the world is on the verge of collapsing into chaos from a disease whose origin is unknown. Many experts and organizations have their theories and ideas on how such a disease emerged and started to systematically destroy our very way of life, but one fact is clear to all. Whoever perishes from the disease gets up and kills, and the people they killed get up and kill".

With the new update that was announced on Steam on September 1st it brings in a whole lot of improvements.

Key Changes

Source Engine upgrade

• Added 64-bit support, 64-bit binaries will automatically be launched on systems with a 64-bit OS.
• Added a borderless window option to video settings.
• Added bicubic lightmaps (from Half-Life 2: 20th Anniversary Update).
• Added radial fog (from Half-Life 2: 20th Anniversary Update).
• Added Steam Networking, port forwarding is no longer required.
• Added UI scaling for high-resolution screens.
• Added Vulkan renderer, which is now enabled by default on Linux.
• Fixed a prediction bug where if the player was moved on the client, their input-based movement for that tick was not taken into account in non-player actions.
• Fixed an issue where certain variables like position would not be updated correctly to match the server in certain situations.
• Fixed certain breakable props not gibbing correctly.
• Fixed player hull being mis-predicted in certain instances causing rollbacks every frame when e.g. crouching or against a wall.
• Fixed the player's base velocity (e.g. conveyors, moving items etc.) getting subtly out of sync from client/server.
• Improved networking precision for local player positions, resulting in less prediction errors and better game-feel.
• Improved prediction for walking on props and other entities.
• Made the game launch in native resolution by default instead of 640x480.

Additions

• Added a menu in the Create Server dialog that selects a server type for Steam Networking, allowing public / friends-only / unlisted servers without port forwarding.
• Added ability to pause the game when playing in Single Player mode.

Changes

• Active Workshop map is now distributed to connecting players on local servers.
• Certain HUD elements such as player names are now hidden during suicide blackout.
• Changed default server name to "'s server".
• ConVar "viewmodel_fov" is now saved to user config.
• Difficulty is now displayed in the server browser game description.
• Flashlight shadows are now independent from "High" shadow quality, and can be enabled in the advanced options (off by default to reduce engine crashes).
• Improved native Linux support for significantly better performance.
• Optimized network bandwidth on player and zombie movement.
• Optimized zombie performance even further on crowded maps.
• Overhauled rich presence to support connections for Steam Networking, both Discord and Steam will now recognize such servers for joins and invites.
• Removed warning dialogs for NAT connection and Steam Deck compatibility as those are no longer relevant.
• Revised voice status icons over player heads to be more readable in darker maps.
• Updated FMOD Engine to version 2.03.12.

Fixes

• Fixed extracted players occasionally appearing as "deceased" on the scoreboard.
• Fixed false spawn notifications (i.e. sound plays and window flashes while "waiting for spawn point").
• Fixed ironsights not being turned off when contemplating suicide.
• Fixed particle rain collision, contributed by BigHatMarley (#1579).
• Fixed several issues when restoring saves on maps that utilize level transition.
• Fixed supply crate and keypad panels not properly resizing on resolution change.
• Fixed zombie idle vocalization cutting short on longer moans.
