The final version of Polish Duel Mappack has been released today. It is a set of five maps designed for 1-vs-1 fights (most of the maps have also 2-vs-2 option) for Q3 CPMA. The pack can be grabbed from the official PlDuel page - there you'll find a list of available mirrors and a lot of interesting informations about the maps and their makers.
You can check the pack in practice at Swelt's server.
Have fun!
