It is set in a fictional post-apocalyptic world, where robots struggle over the relics of human civilization.
Although it resembles some RTS games, unlike most RTS games NERO
consists of two distinct phases of play. In the first phase individual
players deploy robots in a "sandbox" and train them to the desired
tactical doctrine. Once a collection of robots has been trained, a
second phase of play allows players to pit their robots in a battle
against robots trained by some other player, to see how well their
training regimens prepared their robots for battle. The training phase
is the most innovative aspect of game play in NERO, and is also the most interesting from the perspective of AI research.
