About the base game:

It's the year 2040. The world has been hit by sudden dinosaur epidemics, posing a threat to humanity's very survival. But there is still some hope. Aibius, a company, has created Leviathan, a super-advanced AI that can forecast the location of future breakouts. This technology allows people a chance to fight back against the saurian swarms alongside Aibius's ground-breaking exosuits, or powered suits. Exofighters, sometimes known as exosuit pilots, are in high demand.
