Most of humanity was enslaved and abducted to the Vaxxian home world, although a few human scientists managed to escape. Major Havoc is a vector-based shoot-em-up and platform game in which the evil Vaxxian Empire overran the galaxy many years ago. Once players have successfully entered the warp code, they are transported to a higher level. The Breakout game begins and must be played while moving the joystick to the '3'. For example, the RED WARP requires the number '23', so the player must move the controller left or right until the first digit matches '2', then must press the fire button. The mini-game is available at the start of each wave and the way it works is this: a two or three-digit number is displayed and players must move the controller until the number matches the one required to warp. The warps are activated by a utilizing a Breakout-style mini-game at the bottom-right corner of the screen. Major Havoc features a warp system that allows players to skip levels and gain bonus points or extra lives.

I have read this many times but never actually gotten the warp to work (that I remember) I found them online here: Major Havoc (rev 3) - MAME machine ()

Here are the notes that appear in MAME for me for this game.
