Citadel v3 0 addon

First of all, make sure you have patched Quake II to the current, final version 3.20 - Citadel will not work with the retail version of Quake II, so download and install the patch if you haven’t done yet (an unofficial 3.24 patch does exist, and Citadel works fine with it as well). To install and play Citadel follow these steps:

1) Create a new folder named citadel in the Quake II folder (the same folder containing QUAKE2.EXE), and extract all files contained in this ZIP archive into it.

2) Right-click on QUAKE2.EXE and select Create Shortcut. Right-click on the newly created shortcut and select Properties. In the Properties, modify the Target line by adding +set game citadel (with one space before the "+" symbol, this is very important), as in the following example:

"C:\Program Files\Quake2\quake2.exe" +set game citadel

3) Move the shortcut to wherever you want and double-click on it to run Citadel. You will be brought directly to the menu. Start the game and select your favourite skill level as in normal Quake II (or load a saved game).

Note for Knightmare users:

Citadel is fully compatible with the popular custom engine Knightmare. If you have Knightmare installed on your computer, use KMQUAKE2.EXE (instead of QUAKE2.EXE) to create your modified shortcut.
