= Action Quake 2: how to setup and start playing
[[https://en.wikipedia.org/wiki/Action_Quake_2|Action Quake 2]] is predecessor for a popular game "Counter Strike" made by [[https://en.wikipedia.org/wiki/Minh_Le|the same developer]]. It is fully free software now, so it is a good game to play if you prefer using mostly free software. Gameplay is something in between Counter Strike and Quake 2, I would describe it as "It is CS, but fun and it is arena shooter".

== How to setup
There are two ways to play the game. Easy and proprietary one and mostly free, but a bit harsh (not so harsh, but it might require a compiling software depending on distribution you are using).

=== q2pro + aq2-tng + baseq2 + @zevlg config
[[https://github.com/zevlg|@zevlg]] is Emacs package developer who plays action quake for 20+ years. His config is good for competitive playing. If you are not comfortable with playing quake, it might feel awkward.

=== Compiling q2pro
Q2PRO ([[https://github.com/skullernet/q2pro|Source Code]]) is enhanced client for quake 2. It might be not packaged or outdated for your linux distribution, so you need to compile it yourself. It is easy and done using several commands as [[https://github.com/skullernet/q2pro/blob/master/INSTALL.md|q2pro documentation states it]]:

{{{#!bash
git clone https://github.com/skullernet/q2pro.git

sudo apt install meson gcc libc6-dev libsdl2-dev libopenal-dev \
                 libpng-dev libjpeg-dev zlib1g-dev mesa-common-dev \
                 libcurl4-gnutls-dev libx11-dev libxi-dev \
                 libwayland-dev wayland-protocols libdecor-0-dev \
                 libavcodec-dev libavformat-dev libavutil-dev \
                 libswresample-dev libswscale-dev

meson setup builddir
meson configure builddir
meson compile -C builddir

sudo ninja -C builddir install
}}}

It should work for Debian-based systems (Debian, Ubuntu, Linux-Mint and so on). If you have different system only part with `apt install` (dependencies) should change. After running this command you should be able to call `q2pro` binary in your terminal. For example: `q2pro --version`.

=== baseq2
Run `q2pro`. By running this it should create `.q2pro` folder in your home directory (`~`).

It should complain about lack of the baseq2:

{{{
$ q2pro
------- FS_Init -------
Current search path:
/home/w96k/.q2pro/baseq2
/usr/share/q2pro/baseq2
-----------------------
------- R_Init -------
Using video driver: x11
Using GLSL rendering backend.
********************
FATAL: Couldn't load pics/colormap.pcx: No such file or directory

}}}

`baseq2` is the quake 2 game itself. Quake 2 is proprietary game, but the source code of the engine was released long time ago. Yet the source of the art, sounds, models and so on is not free. Some games share this model like [[https://warsow.net/|Warsow]].

So, you need to aquire baseq2 yourself by buying the game. Or basically downloading it elsewhere, but I didn't say this. You can buy Quake 2 here:
- [[https://www.gog.com/en/game/quake_ii_quad_damage|GOG]] (DRM-free)
- [[https://store.steampowered.com/agecheck/app/2320/|Steam]]

By the way Enhanced Quake 2 is good in case if you never played Quake 2 before.

Just buy it, look for installed folder and copy paste baseq2 folder to `~/.q2pro/baseq2`. For steam version on linux it would be `~/.steam/debian-installation/steamapps/common/Quake \ 2/baseq2`.

==== aq2
So we god quake2

=== aQtion using Steam
The most easiest way, but semi-proprietary since it uses Steam. You can install it in Steam, it is completely free and user friendly: https://store.steampowered.com/app/1978800/AQtion/

Also it provides its own packages, that can be run without Steam:
https://github.com/actionquake/distrib (check Releases). Just install package on your system and play.
