The weapon system is based on Radio Allergy, but it uses an unique D.F.S. bomb system.
Bomb can be used when SP gauge is full. When bomb is activated, a barrier surrounds player, which can damage contacting enemies. At the duration of bomb activation, player is invulnerable. Enemy destroyed by barrier provides more experience to player.
Player's shot, sword, shield can be upgraded by using experience item dropped from enemies, with maximum of 100 levels. Weapon levels also act as score multipliers.
