Cave Story+ Steam Update Adds Co-op and Mod Support on December 4 2026

The new Cave Story+ update for Steam brings features like two-player co-op and mod support, matching console versions. This update adds many new ways to play.

A substantial, unexpected update has been deployed to the Steam version of "Cave Story+", bringing it in line with its console counterparts and introducing long-awaited features. The patch delivers significant visual upgrades, official mod support, and gameplay refinements that many observers suggest may finally solidify the Steam edition as the definitive experience for this influential indie title.

The update finally syncs the Steam version of "Cave Story+" with later console releases, incorporating features such as two-player co-op mode, enhanced visuals, and crucially, official support for player-created modifications. This integration allows for custom graphics packs, new challenges, and alternative soundtracks, greatly expanding the game's replayability and customisation potential.

Gameplay and Visual Tweaks

Beyond the headline additions, the patch also addresses some lingering gameplay issues. Notably, a problem where weapons would prematurely level up has been corrected, ensuring a more consistent progression. These gameplay tweaks, coupled with the visual enhancements ported from the Nintendo Switch version, aim to modernize the over-21-year-old game for contemporary players.

Modding Opens New Avenues

The introduction of official mod support is perhaps the most significant long-term implication of this update. Previously, modding "Cave Story" often required fan-made patches or workarounds. The official integration signals a more robust and accessible ecosystem for user-generated content, potentially breathing new life into the game for existing fans and attracting new ones curious about its expanded possibilities.

Background

"Cave Story", originally released as freeware in 2004 by Daisuke "Pixel" Amaya, garnered widespread critical acclaim for its compelling narrative, tight gameplay, and memorable soundtrack. The commercial "Cave Story+" version, published by Nicalis, later appeared on various platforms, including Steam. This recent Steam update arrives more than a decade after the game's initial release on the platform, an unusual timeframe for such a comprehensive overhaul. Previous discussions and community forums have often highlighted discrepancies between the Steam version and other console ports, making this update a notable event for the game's dedicated player base. Reports indicate that the game is also confirmed to run successfully on SteamOS, with some minor notes regarding controller configurations.
