Godzilla: Unleashed

Like its predecessors, Godzilla Unleashed plays as a 3D fighting game with the option to play with up to four monsters in free-for-all or team battles. While the PS2 version involves only button presses, the Wii version uses a combination of button presses and motion control using the Wii Remote and Nunchuk. Basic punch and kick attacks are through the A and B buttons while more powerful and aggressive strikes require swinging of the remote up, down or sideways while pressing A and/or B. Movement is done by the analog stick on the Nunchuk, and flicking it upwards allows players to jump.

Flicking both the remote and Nunchuk allows monsters to grab nearby opponents or environmental objects, and throw them. Weapon and beam attacks also return, but are much weaker and do not lock on. However, they can be sustained for much longer periods. Rage Mode from the previous games is absent, but monsters can achieve "Critical Mass" by destroying the energy crystals found in arenas, which causes them to increase in size temporarily, glow red (similar looking to Burning Godzilla from Godzilla vs.

Unleashed occurs 20 years after Godzilla: Save the Earth, beginning when a meteor shower causes climate shifts and earthquakes. Simultaneously, monsters of Earth begin attacking cities across the globe due to crystals growing on the ground. The Vortaak, returning from the previous games, chose to invade and use the crystals to seize Earth. Factions form among the members of Earth and the monsters, totaling four monster factions: Earth Defenders, made up of natural monsters protecting their territory; Global Defense Force, made up of mechas built to protect humanity; Aliens, made up of allies of the Vortaak invaders; and Mutants, made up of monsters drawn to the power of the crystals. Choices in the story affect later events, including the relationships between Earth and the monster factions.

It is revealed in the finale that the source of the crystals was SpaceGodzilla trying to escape his interdimensional prison that he was trapped in at the end of Save the Earth. The game has four different endings depending on which faction you are on. Earth Defenders and Global Defense monsters remove the crystals, defeat the mutants, run off the Vortaak, and are congratulated by the human forces. Players on the Alien faction destroy the human forces and see Vorticia laugh in victory.

Before the game was released, there was a six page 'designer diary' hosted on IGN that provided some information about working on the game. The first interview of the game with Pipeworks stated that the title was completely new and is specifically designed with the Wii Remote in mind. There were also plans to use WiiConnect24 support for downloading purposes, but this was not in the completed game. First screenshots of the PS2 version of the game were released during September 2007. A PSP version was also planned.

On October 9, 2007, IGN's development blog has revealed that Heavy Melody created the soundtrack for the game and that every monster has a unique theme song that ties to the overall feeling of their faction. On October 19, 2007, IGN stated that the PSP version of Godzilla: Unleashed was canceled; however, it was said that if the Wii version of the game sells well, they would consider bringing back the PSP version.

Unleashed received negative reviews on all platforms, according to video game review aggregator Metacritic. Play Magazine called the Wii version "among the best fighters for the system", while GameSpot stated, "Unleashed is the worst thing to happen to Godzilla since getting killed by Mothra's babies."

GameSpy praised the large lineup of playable kaiju as "ample fan service" while showing disappointment over the new original kaiju, Obsidius and Krystalak, being "a shame that these guys make the cut while classic foes like Hedorah and Battra are MIA (or confined to the PS2 version in Battra's case)."
