Russian developer Nikita has released a playable demo of Parkan: Iron Strategy, available for download from Games Domain. The demo allows you try out their recently completed 3D action strategy game (story), provided you able and willing to stomach the staggering 210.6 MB download size (not 21.1 MB, as the page inadvertedly shows). Warning: The ZIP file appears to be corrupt, so you're advised to hold off downloading until a valid copy of the demo is available.
