This mod has been in development since 2007. Some major features are: Corpses of the fallen will now permanently stay, population caps have been increased, and new units. Each faction receives one hero unit, you can play with and against any faction, and there are Heroes, crazy stuff (like The Maus, Powell, zombies,...) can be activated or deactivated in the reward menu. It also contains an Infantry Only mode, Early war mode, No Pop-Cap mode, and Quick Start mode in the victory conditions. This mod is only for fun! If you are looking for complete realism, try another one.
This video called "Man and Blood with Fire and Shells" will show you some future features from the next update of the NHCmod in particular the mini mode "Infantry Only". In this mode you will mainly only have infantry. Some light vehicles, halftracks or light tanks can support the advance of your troops. AT guns and some artillery are still available.
