Multisoft All-Star Rumble

Multisoft All-Star Rumble, known in Japan as Bash! Multisoft All-Star (ぶつけて! マルチソフトオールスター), is a fighting-platformer game developed and published by Multisoft. The game is a crossover between many different Multisoft franchises, including Superstar, Red the Dragon, Delta Cross, Alien Killer, Realm Souls, Star Maidens, and Dimenbeasts.

Gameplay
The gameplay is like the Super Smash Bros. series, but instead of knocking opponents out of a stage to win, players fight until one's health bar has been decreased (like in other fighting games). Different sorts of items can be used, such as the Landmine from Red the Dragon and the Messenger from Star Maidens. These items can either heal, inflict damage or dispense different items. Players also have a meter which can activate a "Flash Attack" once it's full.

In the game's arcade mode, the player chooses a character with which to battle a series of computer-controlled opponents in a specific order, attempting to defeat them with a limited number of rounds in a limited amount of time per challenger. While the player can determine the difficulty level and number of lives, the same series of opponents are always fought. If the player loses all of their lives or runs out of time, they have the option to continue at the cost of a considerable sum of their overall points.

Characters
The game includes one original character, as well as eleven playable characters originating from popular Multisoft franchises. Furthermore, characters have recognizable moves derived from their original series, such as Red's fire attacks and Koji's arsenal of fighting moves. Twelve characters are playable from the beginning of the game and the remaining six characters can then be unlocked by completing different tasks within the game.

In certain scenes, the characters are portrayed as plushies that come to life to fight. This presentation has since been in the sequels, which feature action-figures instead of plushies.

The representation of the story is not very thorough, though some fans point out it has something to do with the God King, which is a blue entity resembling an anthropomorphic goat, gathering the heroes of different worlds (as plushies) to be used as pawns for his plan of world domination while Hina, the original character, is sent to stop him. While this may be a generic concept, fans still consider it to be the story of this game.
