Take customization to the extreme with the Omega Customization System and battle with one-of-a-kind combat units in this all-new third-person shooter mecha game.

Not being restricted to bipedal builds, you can freely customize your mechs to include multiple heads, legs, and arms in whatever positions and angles you choose. Depending on the parts you use, the parameters will vary wildly, so you can build mechs with whatever abilities and fighting styles you wish!

Arm your custom mech to the teeth with every weapon imaginable and blast your way through oncoming enemies. Experience the heart-pounding mecha action that only your Omega Customized units can provide. Destroy enemy units, collect their parts, and customize your favorite mechs even more. Complete a variety of missions as you battle, customize, and then battle and customize some more!

This game supports online multiplayer. Up to four players can cooperate to complete story missions just like in single-player mode. Not only can you experience the rush of tackling missions with friends, but you can show off your favorite mechs you personally customized.

In the near future, the latest space observation telescope discovers an enormous comet approaching the solar system. Its calculated trajectory is not in danger of colliding with Earth, but the effects its massive size would have on our planet and the sun are unfathomable. The damage caused by the resulting seismic, volcanic, and electromagnetic activity is catastrophic.

In response, a large-scale evacuation plan is carried out. Residents, properties, and city functions in areas determined to be affected are almost all relocated to shelters and other regions. In place of its departed citizenry, unmanned AI defense robots called G-Mechs patrol the abandoned areas, effectively turning them into robot towns. The G-Mechs watch and defend the cities, expelling intruders, preventing robberies and accidents, and ensuring structural collapses and fires do not occur. They are to guard the cities until the comet passes and people can return to their homes.

Here enters Four-Seven Security Service. A security company that is dispatched to robot towns no longer inhabited by humans, Four-Seven Security Service provides a variety of defensive services, including crime prevention, building maintenance and repair, and the extinguishing of fires caused by volcanic eruptions. You are a new employee at the company.
