In July 2016 we gained a new inspiration for this ancient project. PWN 2 will be published soon, changed beyond all recognition!
PWN 1 (fullscreen strongly recommended)
An ambitious project in cooperation with Martin Mach, in which you take the role of Chosen Hero and save the Kingdom. The first Massive Singleplayer Offline Role Pwning Game! The best RPG in the world!
But don't be fooled, this is not the first version. The zeroth version (in Czech) has been published in September 2011 and eventually underwent a radical transformation into PWN 1, but the development stalled in October 2013. PWN 1 will be forever left as a functional demoversion with almost no game content.
