Neuro-Evolving Robotic Operatives, or NERO for short, is a unique computer 
game that lets you play with adapting intelligent agents hands-on. Evolve your 
own robot army by tuning their artificial brains for challenging tasks, 
then pit them against your friends' teams in online competitions!.

New features in NERO 2.0 include an interactive game mode called territory 
capture, as well as a new user interface and more extensive training tools.
