Controlling a caterpillar-tread self-propelled gun, the player is tasked with completing each of the game's eleven stages while shooting enemies and avoiding projectiles.Upon release, Assault was met with favorable reviews, with critics applauding the game's graphics, controls and usage of sprite-scaling.When in the air, the player sees a zoomed-out view of the battlefield and can launch long-range attacks against the enemies while remaining completely safe from their shots.[1] Stages also contain large "Jump Pads" that will catapult the tank into the sky when touched,[2] allowing the player to shoot powerful blasts towards enemies on the ground and to view other sections of the map.[2] In the year 2199, Earth reached its maximum population point, causing humans to venture throughout the Milky Way in search of potential new planets to inhabit.After the war is over with humans' victory, humans launched an extensive assessment and discovered that although natives' civilization was more advanced, they had very little concept and experience in waging conflicts, thus lacked a powerful military necessary to fend off invaders and to protect their planet that gave humankind (whose history is riddled with conflicts, arms race and treachery) immense advantage and lead to the downfall of the natives.Fearing that natives, having now experienced a great conflict against foreigners and as advanced as they are would one day rise up to launch a decisive counterattack as well as to secure the further arrival of more human migrants from Earth to settle on this new planet, humans proceeded to militarize the planet by began constructing large fortresses and weaponizing buildings to strengthen their positions.[6] According to former Wolf Team designer Kazuyoshi Inoue, Assault was an influence for Granada alongside Grobda, as co-designer Toshio Toyota was a fan of arcade games.
