Halo: Spartan Assault

Halo: Spartan Assault is a shooter game where players view gameplay from an overhead top-down perspective. On touchscreen mobile devices, players control the character through virtual joysticks--the left stick controls movement and the right stick controls the direction of the character's fire. On Windows 8 PCs, the method of input is a keyboard and mouse, while Xbox 360 and Xbox One players use a physical gamepad. (Wikipedia.org)
