Field of view (FOV)

Create local.cfg[2]
  1. Go to the configuration file(s) location.
  2. Make a text file called local.cfg (if it does not exist already).
  3. Insert the line view.fov = #, where # is your FOV in degrees
  4. Save the file and boot up the game

General settings

Every option can be set in the text-file local.cfg. Just create local.cfg in the appropriate folder and insert the key=value pairs you want to set. For details where to place local.cfg, see Game data

Remapping

Add this (or just some parts) to local.cfg and edit the entries to suit your needs. Everything after a Semicolon (;) is a comment. A single action can be assigned to multiple keys by separating them with a comma.

Key combinations can be specified using this syntax: <Key1>+<Key2>+<Key3>

    "New Requirements: Windows XP, Windows Vista, and anything below macOS 10.12 are no longer supported. The game also now requires SSE2. Furthermore, while ARM macs are supported, unfortunately the code running on them isn’t native yet, so users on this platform should expect a performance loss."
