The Nintendo DS version of Unleashed, Double Smash features gameplay akin to a side-scroller, similar to that of the Godzilla: Monster of Monsters. Although graphically 3D, its 2D gameplay made it similar to titles such as New Super Mario Bros. or Sonic Rush. Using the two-screen display of the Nintendo DS, flying monsters appear on the top screen, while grounded monsters appear on the bottom screen. A multi-player option allows for a different player to control each monster. Critical reaction to Double Smash was largely negative. IGN gave the game a score of 3 out of 10, saying: "None of the recent Godzilla games have been very good, but at least they were fun. Godzilla Unleashed: Double Smash cannot make this claim. It looks terrible, and reduces the King of the Monsters to a mush of no-texture polygons, then puts him in a tedious series of punching planes and kicking boats." GameSpot gave Double Smash a 2 out of 10, calling it "one of the worst DS games ever made," adding: "With a perfect storm of terrible game design, bad play mechanics, and uninspired destruction, this game does what oxidation bombs, volcanoes, and Matthew Broderick couldn't: It kills Godzilla." GameSpy gave the game a 1 out of 5, saying: "This brain-dead combat is perhaps the worst part of Double Smash. Slowly plodding through the stale levels, fighting the same enemies, and using the same techniques to win grows old almost immediately."
The storyline of Unleashed, taking place twenty years after Godzilla: Save the Earth, begins with a meteor shower raining down on Earth, causing climate shifts and earthquakes. Simultaneously, the monsters of Earth begin to attack cities across the globe as a result of crystals growing on the ground. Factions form among the members of Earth as well as the monsters attacking them, totaling four monster factions. Choices within the story affect later events, including the relationships between Earth factions and the monster ones. The Vortaak, returning from the previous games, choose to invade and use the crystals to seize Earth, but their mothership is knocked into San Francisco bay. It is revealed in the finale that the source of the crystals is from SpaceGodzilla trying to escape the alternate dimension he was imprisoned in at the end of Save the Earth. There are four (five as alternate) endings based on the factions; if one wins as an alien, Vorticia cackles maniacally in victory. If one wins as a mutant, the crystals spread at a cancerous rate, proliferating out of control. If SpaceGodzilla wins, the Mutant ending commences, except that SpaceGodzilla is subsequently seen letting out a victory roar. If the GDF or Earth Defenders win, the player's monster is thanked for their bravery as the world returns to normal. If the Earth Defenders, GDF, or Alien acquires all the power surges, Miku said that the monster became corrupted and it was the only hope. Contrary to popular belief, It doesn't have alternate endings yet in which an Alien or Mutant turns face and saves the Earth(essentially false rumors).

The game consists of 12 total levels: the player first must defeat all six monsters, with the last monster being oneself, but in a different palette. Then the player must defeat the six monsters again, in the same order, but this time in different cities

The Genesis version of Mighty Morphin Power Rangers: The Movie is a side-scrolling beat-'em-up that can be played by up to two players, where the player can control both the Rangers themselves and their Zords (depending on the level). The game consists of six stages, with the first two stages and the final one covering events from the film, whereas Stage 3 to 5 are set before the events of the film and adapts key episodes from the TV show's second season (namely "White Light", "Ninja Encounter", and "Power Transfer"). The game's soundtrack, composed by Hikoshi Hashimoto, features hard rock arrangements of Ron Wasserman's original TV themes. The game contains a total of nine rangers: Tommy, Adam, Kimberly, Billy, Aisha, Rocky, Zach, Trini, and Jason. When selecting Jason, Zach, and Trini, the voice clips of Adam, Aisha, and Rocky are heard when calling out their respective Zord name as their morphing command. The reason for this is because the original actors for them were released from contract after the events of the Power Transfer two-parter episode of Mighty Morphin' Power Rangers. Sega and Banpresto asked for permission from Saban Entertainment to use their characters but have the three replacements use their voices instead of Jason, Trini, and Zach. There are cinematic scenes in digitized form that are abridged from the movie and some from Season 2 of the show. Lord Zedd, Goldar, the Putty Patrol, and Oozemen appear as sub-enemies. Nimrod the Scarlet Sentinel, AC, and DC are renamed in this title as Sentinel Neck, Sentinel Ear, and Sentinel Ring respectively. Players also can fight the Ecto-Morphicons using Ninja Megazord or Falcon Zord (both by 2-Player mode; Thunder Megazord and Mega Tigerzord against the Sentinels). Bulk and Skull also appear as cameos in the game's ending.

Up to three players, as the Battletoads, brawl aliens and mutant rodents through six levels to save the universe from the Dark Queen. The game also includes vertical and bonus levels. Each Toad has its own signature attack, and as customary for the series, players can knock enemies towards the screen, breaking the fourth wall. Rare took greater liberties with violence and gore in Battletoads Arcade since the product was not destined for home consoles. It was Rare's first game to use the 3D graphics technology that was implemented in Donkey Kong Country and Killer Instinct. Although the game playtested well and appeared financially viable, the publisher hesitated to release the game. A port for the Super Nintendo was in production but canceled. The game received its console debut when it was emulated in the 2015 Rare Replay, a compilation of games from Rare's history for the Xbox One.
