Alzadick: Summer Carnival '92

Available at one of the yearly competitions where gamers compete against each other, Alzadick is not a full game, but a brief score-based shooter in the style of the 5-minute caravan modes in Hudson's 'Soldier' series. The usual collect-a-weapon system applies here, and there are also story modes which are nothing more than the score attacks with a bit of background text (in Japanese) to explain what is going on.
