Laser Cannon 1 takes place in a specialized area within Prison Hall.
Laser Cannon 1 is played entirely from a 2.5D side-scrolling perspective. In terms of layout, this secret stage is a straight path with several twists and turns. The details of the level layout may vary however.
The main obstacles encountered in this secret stage are the titular laser cannons. These obstacles consist of rotating wheels that each emit two laser beams in opposite directions. If the playable characters touch these lasers, they will take damage. However, the lasers cannot pass through solid surfaces, meaning the player can avoid them by hiding behind platforms and walls.
When beginning this secret stage, run to the right and climb the ledge there before the local laser cannon can get Sonic/Shadow. Once on safe ground, follow the path to the next section with a laser cannon. Here, the player has to scale the local platforms while dodging the cannon's lasers. After getting out of the laser cannon's reach, the player has to take the passage on the right. However, this passage will have three laser cannons along it.
At the end of the passage, the player has to enter a series of Dash Rings, which will carry the player to the next section, which has a laser cannon sweeping the whole area. Here, the player has to climb the local platforms, which lead to the goal above the section, while dodging lasers.
