Shoop da WOOOP!!!
After selecting "New Game", click Dr. Heiter's name (the word "Heiter" specifically) on the first line of the synopsis and it'll change to Dr. Laser. A sentence should appear at the bottom that reads "perma-laser enabled, high scores disabled", so if you wanna just kill the weird fuckers in copious amounts without it amounting to anything, you're welcome. Also, great game!
