Secret Later Weapon and Energy Power-Up
Star Soldier is a really tough game, but with the super secret power-up you can blast your way through the game with multiple firepower and a special laser beam weapon that you won't find anywhere in the game!
To initiate this awesome trick, before turning on the game, hold the 'A' and 'B' buttons while pressing up and to the left on the controller one pad while pushing the controller two pad down and to the right. While this is being done, turn on the unit and during the title screen press the 'Select' button on the controller one pad ten times. If you did everything right, the screen will flicker for just an instant - this lets you know that the trick has been done.
Press 'Start' to begin play and hit 'Select' to switch to the special laser weapon that wipes out everything! You can switch back to regular fire by pressing 'Select' again. The laser is especially effective on the Star Brains.
