The player controls the titular character, Major Rex Havoc, first in the "
shoot-'em-up" style game, in which the player operated Major Havoc's spaceship, the Catastrofighter, against the numerous robot ships who defend the enemy space stations. The ships are encased in a sort of "
buckyball" force-field shield which must be shot first before the ship can be killed. In the next phase, the player lands on the robot space station by centering the Catastrofighter in between the moving white line and Major Havoc would exit his ship and enter the space-station. The roller-knob controlled left and right character movement and a "jump" button permits the player's character to leap over obstacles. The object is to get to the core of the space station, sabotage the reactor, and escape to a minimum safe distance before the space station explodes. Red arrows point the direction going in and the word "OUT" appears on the arrows during escape to point the direction out. The levels get gradually more complicated and difficult to navigate as the player progresses. Upon a successful mission, the next space station becomes more difficult and the time allotted (both in and out) is decreased. The game includes a "warp system" that lets the player to skip levels and gain bonus points. Warps are activated by a
Breakout game at the bottom-right of the screen, where there are two- or three-digit numbers. The player has to move the roller controller until the number matches the number required to warp. For example, the red warp requires the number 23, so the player moves the roller to the right or left until the first digit matches 2, then the player clicks the fire button, the
Breakout ball starts moving, so the player has to play the game while moving the roller to the 3 at the same time. When the player enters the warp code, the player is transported to a higher level. Extra lives are earned not only by achieving a certain number of points, but also by completing the
Breakout mini-game. ==Reception==
