How do I sprint without holding Shift in KF2?

Edit KFGame\Config\DefaultInput.ini, find the LeftShift binding that runs GBA_Sprint and replace the command with Toggle bRun. A second option appends | OnRelease GamepadSprint to the original command.

How do I join a server by IP?

Open the console with the key left of 1, then type open followed by the IP address and port, for example open 123.123.123.123:7777.

How can I find the IP of a server I played on?

In Steam use View, Servers, History (or Favorites), change the filter to Killing Floor 2, right-click the server and choose View server info to see the IP address.

Binds & Console

KF2 Scripts and Console Commands: Auto-Sprint, Dosh Macro, IP

A short community collection of quality-of-life tweaks for Killing Floor 2: a config edit for auto-sprinting, a mouse macro for throwing dosh quickly, and the console commands people use most. The original guide also listed community RPG-style servers, but that list was tied to 2016 and is not repeated here. For more binds see KF2 setbind keybinding guide and toggle sprint console binds.

Auto-sprinting

Open ...\Steam\steamapps\common\killingfloor2\KFGame\Config\DefaultInput.ini.
Find the line .Bindings=(Name="LeftShift", Command="GBA_Sprint").
Option A (recommended): replace the command so the line reads .Bindings=(Name="LeftShift",Command="Toggle bRun").
Option B: use Command="GBA_Sprint | OnRelease GamepadSprint" instead.

You may also bind the Toggle bRun line to an unused key such as L rather than replacing Shift. After that you keep sprinting without holding the key.

Fast dosh throwing with a gaming mouse

For Logitech mice such as the G300, G500 and G700:

Open the Logitech Gaming Software.
Go to Multi Key, record a keystroke, press B (the default drop-cash key) and stop recording.
Set the repeat option to While Pressed with a delay of 25.

The same approach can be used for rapid fire on the middle mouse button and similar tasks.

Console commands

Open the console with the key next to 1 (the backtick or tilde key).

Connect by IP: type open <IP address>:<port>, for example open 123.123.123.123:7777.
reconnect - rejoin the latest server.
disconnect - leave the server.
suicide - kill yourself instantly.
exit - close Killing Floor 2.
say <text> - send a chat message from the console if you cannot type in the chat box.

Finding the IP of a server you played on

In Steam, open the View menu and choose Servers.
Open the History tab (or Favorites).
Use Change Filter, pick Game and select Killing Floor 2.
Right-click a server, choose View server info and read the IP address.
