Robot Battler is an action game for up to two players in which the goal is to create the superior robot battler. The game was exclusive to the Sega Meganet service, available only in Japan, but was later added to the Game no Kanzume Vol. 2 and Game no Kanzume Otokuyou compilations.
The player(s) first distribute stat points and then spend a separate resource to acquire ranged and melee weaponry. They then fight each other, or a CPU opponent in the single-player mode, until one robot falls. Judicious use of cover and pouncing on weaknesses in the opponent's build is the key to victory.
