Avenging Spirit

Players can possess one of four characters with unique abilities at the start of the game, but the library of enemies expands and changes with each level. Players either attack or possess enemies, collect power-ups, and defeat bosses to advance.

During a walk with his girlfriend, the player is ambushed by agents of a mysterious crime syndicate who take his girlfriend away and shoot him to death. Now, as a wandering spirit with the ability to possess most others, he is summoned by his girlfriend's father (who researches ghost energy) and is given a mission to save her from the mysterious crime syndicate holding her hostage, enabling the player to rest in peace.

Coincidentally, the crime syndicate is also researching ghost energy, and they kidnapped the girl in an effort to force her father to cooperate with them. The player must fight through six stages to infiltrate the evil syndicate's base, collecting three keys on stages 2, 5, and 6. If the player has all three keys upon reaching the final leg of Stage 6, he can open the girl's cell and possess her to help her fight her way out. If not, he must abandon her and face the syndicate's leader alone.

In Japan, Game Machine listed Avenging Spirit on their July 1, 1991 issue as being the seventeenth most-successful table arcade unit of the month.

Sinclair User called Avenging Spirit a "superior action game with a rather odd scenario." They praised the longevity of the game, but admitted that it had a steep learning curve which might not appeal to more casual players. British gaming magazine The One reviewed Avenging Spirit in 1991, stating that it "isn't destined to be a classic", but it has "originality and nice touches".
