Killing Floor Fast Download Guide

Nothing is worse than joining a server and staring at a “Downloading package…” screen that moves at 10KB/s. This guide explains why this happens and how to fix it.

Why is it so slow? (The Technical Reason)

By default, Unreal Engine 2 games download files directly from the game server process (UDP channel). This is incredibly slow and caps out at very low speeds (~10-15KB/s).

The Solution: HTTP Redirect (FastDL)

Good servers (like ours) use HTTP Redirect.

1. When you connect, the server tells your game: “Don’t download from me. Go to this URL.”
2. Your game connects to a high-speed web server (Nginx/Apache).
3. You download the map at full speed (100MB/s+).

If you are downloading slowly on our server:

• Check your firewall. It might be blocking the HTTP connection from the game.
• Check your KillingFloor.ini. Ensure AllowDownloads=True.

How to Install Maps Manually

If downloading ingame fails or is stuck, you can install files manually.

1. Find the Map: Search for the map name on Google (e.g., “KF-Defence-B2 download”).
2. Download it: You usually get a .rom file (Map), .utx (Textures), or .ukx (Animations).
3. Place it in the folder:
   • Maps (.rom) -> KillingFloor/Maps
   • Textures (.utx) -> KillingFloor/Textures
   • Sounds (.uax) -> KillingFloor/Sounds
   • Music (.ogg) -> KillingFloor/Music
   • Static Meshes (.usx) -> KillingFloor/StaticMeshes
   • System (.u, .int) -> KillingFloor/System (Be careful overwriting System files!)

Cache Folder Tip

When you download from a server, files go into the Cache folder, not Maps.

• Location: KillingFloor/Cache/
• Index: The file cache.ini links the weird filenames (e.g., 45A2C...) to real names.
• Tool: You can use “KF Cache Extractor” tools to convert these cached files into real files if you want to play them offline in Solo.
