The game features a fairly distinct setup for its levels for the fighting genre, as each allows the player to select from two different opponents. One of the more memorable features of this game is that Godzilla's appearance will change depending on who he is facing. Unfortunately, the major trade off here is that the player can only select Godzilla in the game's normal mode.

	Level 1
		Opponent: Anguirus Stage: Osaka Godzilla: 1955		Opponent: Rodan Stage: - Godzilla: 1964
	Level 2
		Opponent: King Ghidorah Stage: Planet X Godzilla: 1965		Opponent: Gigan Stage: World Children's Land Godzilla: 1968
	Level 3
		Opponent: Hedorah Stage: Mount Fuji Godzilla: 1968		Opponent: Megalon Stage: - Godzilla: 1973
	Level 4
		Opponent: Mechagodzilla Stage: - Godzilla: 1973		Opponent: Biollante Stage: Lake Ashinoko Godzilla: 1989
	Level 5
		Opponent: King Ghidorah Stage: - Godzilla: 1991		Opponent: Battra Larva Stage: Philippine Trench Godzilla: 1992

The game's last selection of stages presents a variety of options, depending on how many points the player has managed to achieve through the previous levels. There are a total of six possible stages to choose from, with a varying degree of difficulty that does not directly correspond to how many points it takes to unlock. It should also be noted that reaching a high score does not lock the player into facing a particular opponent. For example, a score of 550,000 could be achieved but the player can still pick to face the Super-X2 if they desire.

		Opponent: Super-X2 Stage: Osaka Score Required: O - 449,900
		Opponent: Mechagodzilla II Stage: Yokosuka Score Required: 450,000 - 499,900
		Opponent: Biollante Stage: Wakasa Bay Score Required: 500,000 - 549,900
		Opponent: Mecha-King Ghidorah Stage: Shinjuku Score Required: 550,000 - 599,900
		Opponent: Battra Imago Stage: Minato Mirai 21 Score Required: 600,000 - 649,900
		Opponent: Super Mechagodzilla Stage: Makuhari Bay Area Score Required: 650,000 or over

After someone's first plays through the game, reaching the end and looking at the total scores required to unlock all of the stages, it can be a pretty shocking realization. Most people should only be able to access the Super-X2 on the first play through, while playing a second time should place allow a player to access up to the Biollante stage with more experience. Play well, without using a continue, and you can reach up to Mecha-King Ghidorah. However, there are still two stages left, so how does one achieve a score that high?

The answer, rather sadly, are "perfect bonuses". These bonuses are achieved from flawless victories, where Godzilla took no damage, and award 50,000 points. To put it into perspective, the total for a normal round can be around 65,000-75,000. So this bonus is rather substantial.

Unfortunately, a player will need 2-3 of these perfect bonuses, depending on how well they do with the rest of the matches, while also doing the bonus rounds successfully and not using a continue. If that sounds daunting, it's because it is. There is no simple or easy means of accomplishing that, and frustration is sure to follow as achieving perfect finishes are inevitably up to luck in terms of what the computer player decides to do. As a general recommendation, it's probably best to attempt perfect finishes against Rodan, King Ghidorah (Showa) and Mechagodzilla (1974).
