Try to charge your beam as much as you can
-Blue(X)beats green, Green (triangle) beats red, and Red (square) beats blue
-Wait ti'll you see what your opponent plays their color then play the color that beats it
-Monsters that CAN play beam fights are both Mechagodzillas, Mothra (ADULT ONLY!), Spacegodzilla (YAY!), both Ghidorahs, Megalon, Rodan, and Godzilla 2000 and Godzilla 90's
I do not know about Megurius, you might want to test him with a friend before you go out there with him. I look forward to seeing you online in the game. I will play as Spacegodzilla!
When you get grabbed by a monster (other than flying) press all attack buttons and move analog stick around. You should fall and the opponent will get dizzy. At this time you can take a free hit.
Go to purchase. Then press x on monsters. There you can buy packages and within them are monsters. [The way you get money is beat action.]
First, you must unlock Jet Jaguar. When you battle Megalon and he goes underground, turn small and run past him. Hopefully, Megalon will jump out, miss you, and become dazed. When he does, HIT EM' HARD!
Get Spacegodzilla,Jet Jaguar, and King Ghidorah
To do this cheat you must beat adventure mode twice as Magalon and Godzilla[90s or 2000].
