It is fun but not tested enough variant.The idea is having always 3 monsters in the game. One player controls monster being in Tokyo, other player controls 2 monsters outside. But players will unlikely control the same monsters during whole game (see following rules).
Setup
The players decide who goes first. Then first player chooses 1 monster to play initially with, and second player chooses 2 other monsters. The monsters are placed around Tokyo as in normal 3-player game. Since then the turn order for monsters is not changed during the game.
First turn rule
This rule is for the first turn of the first player only. After all dice rerolls if there is no attack result, then second player must choose and turn one die to show attack result. So after first turn there will always be one monster in Tokyo.
Course of the game
Three monsters go in turn order as if in 3-player game. For all game effects monsters treated as enemy to each other. However, owner of each monster can be changed. One player controls a monster being in Tokyo, other player controls 2 monsters outside the city. When a monster enters Tokyo, the player controlling that monster keep control of it, but lose control of the other monster. And the player controlling escaping monster keep control of it and take command of second monster being outside Tokyo.
Winning the game
The game is over when a monster scores 20 victory points or a monster dies. The winner is determined in following way: 1. The current owner of the alive monster with 20+ victory points wins. 2. If only one monster dies, then his current owner loses the game and his opponent wins. If two monsters die simultaneously, then owner of last standing monster wins.
Enjoy!
