To all of you Portal nay-sayers out there I have this to say: CHEAT! I beat the game and after losing the fun part of the game, decided to look up cheats to spice up the video game fun! Spoiler to all BUT! If you go to options, keyboard, and enable the enabling the console by pressing `, you can open the Cheats menu...If you input the correct command you get new stuff to make puzzles easier; Like a what-if? "What if I could get through that puzzle without having to go through all that nonsense?" And cheat spoiler: typing in Impulse 101 gets you the original (I think) weapons from HL 1-2, but also the full portal gun if you haven't gotten that far...you can also spawn HL-2 zombies, civilians, hell even combine soldiers! my point is, the game doesn't have to lose it's tastelessness if you give cheating (AFTER BEATING IT SO YOU DON'T NERD RAGE ME!)a try...The Cake is not a lie.
