Morphid in NEP has 3 types of infantry units:
Light infantry, Heavy infantry and proton infantry.
Now we have models for it but only light infantry is in game at the moment.
Light infantry is good for capturing buildings. It is very fast. Making plague of alien's infantry i very funny, and easy. If enemy have not enogh infantry to stopi it, it can very fast enter inside buildings and capture it.
I will said something about new infantry when it will be added to the game.
I am writing new scripts for AI. New script will improve the units production. When I finish it I will test campaign.
