Zoids Assault is the re-imagining of the Zoids universe based on the toy model franchise. It is a strategy game with RPG elements that features giant robots. The player takes charge of Maroll's 99th Zoid Platoon, Mace Squad, and leads a covert mission behind enemy lines into Jamil alongside Sgt. Jessica Lambert and the commando squad known as Katana. The zoids can be customized with parts claimed from defeated foes to build up a force that can get a stronger grip on the battlefield.
The player controls a small team of five zoid pilots, each with their own special skills and roles within the squad. Customization options allow players to tailor their units to suit different playstyles. However, due to being outnumbered, mastering key tactics such as cover fire, coordinated attacks, and EMP systems is crucial to success.
The mission's long odds are amplified by the fact that the player must operate behind enemy lines. To achieve victory, the player must carefully manage their team's strengths and weaknesses, all while keeping an eye on resources and progress.
