Features What this web version adds

Works in both Jedi Knight and Mysteries of the Sith.

Getting Started

1. You need Jedi Knight: Dark Forces II installed on this computer, for example from Steam or GOG. In Steam, right-click the game, then choose Manage, then Browse local files to see where it is.
2. Click Play JKDF2, any room, or Join or Host in Nar Shaddaa or Sith: Asteroid, then pick the game's folder: the one with the episode and resource folders inside. A room asks for its own game's folder.
3. Just before the game starts, untick Play in fullscreen to play in the browser window instead. The choice is there every time, and this browser remembers it.
4. When the game starts, choose Multiplayer to host a match or join one.
5. To play with mods, put them in the game folder: in a mod or mods folder, in a folder of their own, or as a GOB in Resource. GOBs, zip files and unzipped mods all work, and so do JK Patch Commander's patches. After you pick the game folder, each mod it finds has its own checkbox. They start ticked, and you can untick any, or all of them at once with Select all. This browser remembers which you left unticked for next time. Players who join you get them too, and if you join a game with other mods, yours are swapped for the host's. Those are saved in this browser, and you can pick one of them to play on its own next time.

Your Files

• Your game stays on your computer. When you pick your game folder, this page reads the files on your computer and loads them into the game in this browser tab. They aren't uploaded to our server.
• Except custom maps and mods you host. When you host a custom map or play with a mod, players who join without it get a copy from your browser, directly or passed through our server, which doesn't keep it. Files from the original game are never sent: each player's browser fills those in from their own copy.
• Why we ask for the folder. This web version comes with no game files at all, so it only runs from a copy of the game you already have. The check makes sure the folder holds the game's files before it starts.
• About the browser's "upload" message. Your browser may ask whether to "upload" the files. That's its standard wording for letting a page read a folder. The files still stay on your computer.
• You only pick the folder once. The game files it needs are saved in this browser (about 250 MB for Jedi Knight, 500 MB for Mysteries of the Sith, plus your mods), so next time the game starts without asking. If you add mods or maps to your game folder, choose it again from the mod list or from Play JKDF2. To keep no copy, untick "Save the game files in this browser" when you pick the folder.
• Your characters and controls are saved in this browser, so they're there next time.
• So are your screenshots, under Your Screenshots. Clearing this site's data in your browser deletes them, so download the ones you want to keep. It deletes the saved game files too, and the page asks for your game folder again.

Your Screenshots

Press F8 or F12 in a game, or the key you set for screenshots, and the picture is saved here, in this browser. In Edge use F8: Edge keeps F12 for its developer tools.

Game Help

• Use a current Chrome or Firefox on a computer. Phones and tablets can't open a game folder.
• If the page says files are missing, you picked a folder one level too high or too low. Pick the one that has episode and resource directly inside.
• The game needs graphics acceleration. If it won't start, or runs at a few frames per second, turn on graphics acceleration in your browser's settings and restart the browser. This page tells you how when it's off.
