It is a futuristic combination of squash and Breakout, and is a single player game. Cosmic Smash (コズミックスマッシュ) is a 2001 sports video game developed and published by Sega for arcades.

How to Play Cosmic Smash

Here is the default control layout for Cosmic Smash in the RetroPlayers.Club Player. Open Controller Mapping in the app to reassign anything to your own keys or gamepad.

The Story Behind Cosmic Smash

It is a futuristic combination of squash and Breakout, and is a single player game. It is one of the few Dreamcast games to be released in a DVD-style case, rather than a jewel case. The game instructs players (and onlookers) to 'silence their cell phones' before pitting the player in a one-on-one match against an AI opponent defending two target tiles.

A reimagining titled C-Smash VRS was released for the PlayStation 5 via PlayStation VR2 and Meta Quest on June 23, 2023, and Pico 4 on April 4, 2024. After destroying the two target tiles, the game will end, the credits will roll, and the player (if qualified) will be asked for initials for the high score table. If the player completes the final stage of their 'route,' and finishes at least eight stages with a trick shot during their playthrough, they will be awarded with a bonus stage.

What You'll Play

Both the starting time limit and the bonus time can be adjusted. At last update, the highest score on the third-party leaderboard was a two-way tie of 590,678,903—both entries by an English player named "Alex" with a listed age of 11. There are also walls and moving tiles in some stages, requiring the player to bounce shots off of the side, top, or bottom walls of the play area to navigate around.

The game ends when the player runs out of time, or when they reach a special stage at the "end of the line." Depending on the route chosen at each fork, each completed playthrough of Cosmic Smash can have a different number of stages. In addition to 'standard' shots, the player can charge a 'trick shot,' combining them with the joystick to set up elaborate, athletic, and powerful shots. A similar third-party leaderboard was available at the website Solvalou, but has also since become defunct.

Why It Still Hits

It is a futuristic combination of squash and Breakout, and is a single player game. The game instructs players (and onlookers) to 'silence their cell phones' before pitting the player in a one-on-one match against an AI opponent defending two target tiles. This is the only stage with an "active" opponent in the game, and the AI opponent will react according to the player's shot selection.
