Raiden DX

This game expands on the first Raiden' s mechanics, introducing two weapons: the Bend Plasma, a lock-on weapon that deals constant low damage to enemies, and the Cluster Bomb, a fast-deploying bomb that does less damage than regular bombs but strikes a larger area. Raiden II has three primary weapons and two missile weapons, upgraded by collecting power-ups . Primary weapons and missiles are fired simultaneously. Bombs are special weapons that deal damage over a wide area and cancel out enemy fire.

Players can carry a maximum of seven of any combination of the two types of bombs in the game. The player fights enemies through eight stages of increasing difficulty. In a two-player game, when one player shoots the other's craft with the red or blue primary weapon, the other player's craft generates special projectiles that deal a lot of damage to enemies. Plot The game's story continues where the first game left off.

Three years after the VCD repelled the invasion of the Crystals, the remnants of the machines controlled by the Crystals regroup to form another army to resume taking over the Earth. To combat this Crystal resurgence, a new weapon is developed for the Fighting Thunder—designed from Crystal technology—to stop the Crystals again.
