About the Update

This update finally brings all of the later console version additions to the Steam version of the game, including two-player co-op mode. Venture back into the caves—but this time, bring a friend!

You’ll see many visual elements have been overhauled with this update, with the addition of animated dialogue portraits for all characters, enhanced dynamic lighting and water effects, improved environment shading, widescreen support, and more.

As for gameplay, you’ll find a number of helpful tweaks and gameplay improvements have been made. A few spots have had their difficulty minorly tuned or streamlined (like stacking puppies!) plus a Sand Pit Challenge level has been added to the game’s bonus challenge mode.

Even if you think you’ve already seen all that Cave Story has to offer, with this update, the game now supports player-created mods for custom graphics packs, challenges, soundtracks and more.
