'No Man's Land: Fight for Your Rights' was released in 2003. I see PC Gaming WiKi has a page for the game. Whilst browsing the Wayback Machine on the Internet Archive, I saw that their website lists a patch. This patch is not available on PC Gaming WiKi and I have been unsuccessful in finding the patch.
I was thinking about re-installing the game again just to try the campaign once more. Installing a patch for it may help fix possible issues.
Furthermore, I am unaware of any possible modding capabilities for this game. One annoyance, especially multiplayer, was the low max population count. If there was a way to somehow increase this, it would be highly appreciated. The game has no in-game scenario editor either.
