Laser Cannon 2 takes place in Metropolitan Highway. The majority of this extra stage's course leads through a route made up of unbreakable Containers and platforms.
Laser Cannon 2 is played entirely from a 2.5D side-scrolling perspective. In terms of layout, this extra stage is a straight path with several twists and turns.
The main obstacles encountered in this extra stage are the titular laser cannons. These obstacles consist of rotating wheels that each emit two laser beams in opposite directions. If the Avatar touches 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 Laser Cannon 2, the player will start out right next to a laser cannon. Slip past it and follow the path on the right. Along the way, the player has to get around two additional laser cannons. Eventually, after passing this extra stage's second Star Post, the player has to take a Spring up to a higher path and follow it past three laser cannons. At the end of this path, the player must let themselves drop down from the path's ledge so some automatic Wire Attack targets can carry the player to the next section.
In this new section, the player has to follow the path on the right across some platforms over the local bottomless pit while watching out for laser cannons, until they hit a Spring that will send them to the goal.
