Download a pak file below, place it into your action directory, for example C:\Quake2\action\
For AQtion place pak file into Steam\steamapps\common\AQtion\action directory
When downloading the pak the files, make sure Save as type is set to All Files & remove the .bin extention, so the final result is pak10.pak or pak11.pak, for AQtion release make it zzz_protox.pak
Download AQtion Pak File - this will work with Steam AQtion release (no font/scope change, but does include hud, conback & tags)
Download AQ2 Pak File - this will work with clients such as Q2Pro
Download AQ2 Pro Pak File - this is meant specifically for actionquake.net release
Default AQ2 running with Q2Pro & x4 scaling as an example, this release includes new scope & tags.
AQ2 Pro release, only changes hud, numbers & new font can be selected by changing to Action green or Action cyan in menus. AQ2 Pro already offers plenty of scopes and default tags are already good, so I didn't feel like messing with them. New hud & numbers can be changed in menu when normal sizes are selected.
New retro style font with green & cyan styles based on Quake2 conchars but also very different if you compare. If you want to use the green in default Q2Pro, you will need to use a pak file editor (PakScape or PakExplorer for example) to rename congreen.png to conchars.png and rename the cyan conchars.png to something else or remove it inside the pak file.
I made my first Action Quake2 map in 2023, I call it cityscape. You can download it on github, just grab cityscape.pkz and place it into your action directory. Load it with map cityscape or gamemap cityscape in console.
