Omega Crisis

Omega Crisis (オールスターバトル! オメガバトル All-Star Battle! Omega Crisis in Japan) is a crossover fighting video game developed by Eighting and published by Smile Games in North America and Europe, and by Sega in Japan. It features characters from Smile Games, Sega, Bandai Namco and Cartoon Network. Some DLC characters will come from other companies.

Gameplay
The gameplay is a mixture of Tekken and Super Smash Bros.; characters fight in 3D arena while trying to knock opponents off the arena. Every character has a "Omega Super" which builds up during the fight and acts similar to a Final Smash from Super Smash Bros.

Development
While on a trip in Japan with Smile Games of Japan, the founder of Smile Games of America saw an employee of Smile Japan in a break room playing DreamMix TV World Fighters. Inspired, the founder began commissioning a game similar to DreamMix. Smile chose Sega and Bandai Namco as they had crossovers with their characters and Cartoon Network as they had also experienced a crossover, especially with Cartoon Network: Punch Time Explosion.

While in development, the staff of Cartoon Network requested Smile that there should be a character from Teen Titans Go!. However Smile rejected this as the Teen Titans Go! characters were owned by DC and not Cartoon Network. The staff of CN said that the show was important to the channel but Smile threatened to cancel the game. As a result, no TTG character appeared.

Smile Games confirmed DLC content would be on the way, and they would be organized by seasons. The characters will be handled by Smile Games, Sega and Cartoon Network.

Plot
Worlds of Smile Games, Sega and Cartoon Network are brought together by an malevolent entity known as Crex and seeks to take all of them over. It is up to the heroes of the respective worlds to stop Crex.
