Features

Everything in Life Fiber 1.0.2.

01

Rollback netcode

  • Rollback built on GekkoNet, carried over Steam networking. No port forwarding needed.
  • Each player sets their own input delay.
  • See ping, jitter, rollback frames and your opponent's FPS in-game.
  • Wi-Fi/Wired indicators for lobbies and quick match.

02

Quick Match

  • Every player is listed with their character, wins / losses, streak, ping, connection (Wi-Fi/Wired) and status.
  • Challenge anyone who's free. Your input delay starts at a suggestion based on their ping.
  • Save your character once, and change it from the room any time.
  • Quick Match rooms will sort players with the same gameplay mods together to ensure compatibility.

03

Lobbies & spectating

  • Host private matches with a code using Direct Match, which can also be joined as a spectator.
  • The rematch menu has been reworked to offer instant rematch.
  • Hop in any time: When spectating you will always see the whole session start to finish no matter when you join.
  • Spectating is also available in the quick match menu!
  • You can disallow spectating your matches in the settings menu.

04

Mod Support

  • Put each mod in its own folder under Mods. A mod only needs the files it changes.
  • Select from multiple mods and restart quickly in the new Mods menu under Options.
  • Online play compares both players' gameplay files and detects any mismatch before the match. Cosmetic-only mods are allowed!
  • Each mod keeps its own replay folder, so every saved battle plays back correctly.
  • Content mods' extra colours, such as Mako's and DTR's new fourth colour in Restitched, work online.

  • Every colour is available from the start, including the console pre-order Special Colors.
  • Versus, Practice and Gallery modes are unlocked by default.

Settings & Controllers

  • New Options menu combining all vanilla and Life Fiber options.
  • Improved controller mapping menu.
  • Bind actions to triggers (LT / RT, L2 / R2).
  • See custom keyboard mapping during Bloody Valor prompt.

Rendering Improvements

  • Major graphics optimization. Fixes slowdown on AMD devices and improves performance for all platforms.
  • Image scaling improved, offering bicubic upscaling and trilinear downscaling from the current render resolution when resized.
  • Render scale options from 50% to 200% for supersampling.
  • New FXAA Quality and SMAA anti-aliasing options.
  • Low-latency present mode for Windows 10 / 11.

Quality of Life

  • Skip launcher and logos at boot. Fixes Steam Deck launch issue.
  • Bloody Valor soft-lock fixed.
  • Default keyboard binding bugs fixed.
  • "Stage format" labels corrected to match Restitched.
  • Audio output device selection.
  • Manual text language selection support.
  • Updates itself: new versions are offered in-game and install with one confirm.

Image quality

Supersampling and SMAA anti-aliasing. Drag to compare.

Before screenshotassets/media/compare-before.png
After screenshotassets/media/compare-after.png

Render scale

Render the 3D at 50–200 % of your resolution. Go above 100 % to supersample for smoother edges, or below it for weaker GPUs like the Steam Deck. Menus and the HUD stay sharp at any scale.

SMAA

Anti-aliasing: Off, FXAA, FXAA Quality or SMAA, the cleanest edges. All of them add no input delay.

Detect best settings

A new install picks a Low, Medium or High preset for your graphics card and screen. Run it again any time from Settings > Graphics.

Download LifeFiber-1.0.2.zip Release notes

Everyone in a match needs the same build: host, opponent and spectators. The Life Fiber panel's title shows Life Fiber 1.0.2+ef305372.

  1. 1

    Unzip

    Extract dinput8.dll from the zip above.

  2. 2

    Drop it in

    Copy it next to KILLlaKILL_IF.exe. To find that folder in Steam, right-click the game, then Manage > Browse local files.

  3. 3

    Open the panel

    Start the game and press F1, or Select + Start on a controller.

  4. 4

    Fight

    Pick Quick Match to challenge anyone in the room, or Direct Match to play a friend with a 6-letter code.

Steam Deck / Linux

Also add this line to the game's Launch Options (in Steam, right-click the game, then Properties > General > Launch Options):

WINEDLLOVERRIDES="dinput8=n,b" %command%

To uninstall, delete dinput8.dll from the game folder. The mod doesn't change any of the game's files.

FAQ

Do both players need the mod?

Yes, and on the exact same build. Players on different versions can't connect, which keeps matches in sync. Spectators need the same build too.

How do I update?

Life Fiber checks this site for a new version when the game starts. The title screen and the panel say when there is one: Update and restart downloads it, checks it and restarts the game with it. You can also download the zip above and replace dinput8.dll by hand.

Who will I meet in Quick Match?

Everyone on the same Life Fiber version and the same game content (original or the same content mod). Find more players and organise sessions on the KILL la KILL -IF Community Discord.

Does it change my game files?

No. The mod is a single dinput8.dll in the game folder. Content mods load from the Mods folder, and the game's own files stay untouched.

Can I still use the game's own online modes?

Yes, with the original content. While a content mod is loaded, the game's Player Match and Ranked Match are locked, because they would put you against players on different content. Use the Life Fiber panel instead.

Can we play with a content mod like Restitched?

Yes, if both players load the same mod. The lobby checks the gameplay files. If they differ, it shows what's different and the match won't start. Cosmetic differences (models, textures, menus, music) are fine.

I hit a desync or a crash. What should I send?

Zip the lifefiber-logs folder in the game folder. For a desync, send it from both players. Include the match code and roughly when it happened, and post it on the Discord or email it to lifefiberproject [at] protonmail [dot] com.
