Hello friends!
I know that these games are old, although they are still great, and some people still plays it. I looked through my old list of bookmarked websites, and found this - huge library of maps for these games. They've been gathered by people from clan Force Crusaders, one of the best JK2 and JA clans in Poland (like 10 years ago, but as far as I know, they are still playing from time to time).
Maybe you bought JK2 or JA recently on a Steam Sale and tried to play in multiplayer but had no custom maps (and in-game downloading system is crappy and slow), or maybe it will bring some nostalgia to you and make you play once again?
Well, here they are!
