is a 1996 competitive scrolling shooter arcade game originally created by ADK. It was ADK's last production for the Neo Geo platform. The gameplay, which can be characterized as a combination of a fixed shooter and a versus puzzle game, uses combinations of shots, as well as timed power-ups to attempt to damage the opponent. These attacks also serve as counters to the opponent's attack. Gameplay There are two types of standard attacks: a normal shot and a charge-up shot. Each character starts with two bombs, which clean the screen while briefly granting the player invincibility. The two players' playfields are separated by a vertical bar; each playfield is independent of the other. Series of enemies arrive from the top of the screen. The player must destroy them in chains (combos), which will send one or more fireball projectiles the opponent's screen (Normal Attack). Shooting a Normal Attack several times reflects it back as a glowing Reverse Attack. If Reverse Attacks are reflected again, a number of powerful counterattacks in the shape of one or more indestructible enemies appear (Extra Attack). Reflecting many Reverse Attacks at once can instead summon a boss (Boss Attack). The Extra Attacks and the Boss Attack vary from one character to another. The power gauge fills as the player destroys enemies, up to a maximum of three levels. By holding down the fire button and releasing when a certain level is reached, the player can launch a character-specific charge shot to assist in clearing enemies from the player's screen. At Level 1, the charge shot is launched. At Level 2, the charge shot and three Extra Attacks against the opponent are launched. At Level 3 (Max Level), the charge shot and a Boss Attack are launched. Firing charge shots at Level 2 and above will decrease the power gauge. 30–40 seconds into a round, a blue orb appears among a chain of enemies. If this orb is destroyed in a chain, the player achieves Fever status for the next several seconds. Chains created during Fever generate faster and more plentiful Normal Attacks per enemy destroyed, which can prove to be very dangerous to the opponent if large chains are made. Both players are given five life points at the start of a round. Colliding into an enemy costs one life point, but the player cannot be killed this way; if a player has one life
