Start Chapter 1, "Point Of Contact" and collect a sniper rifle. Find the "Gil's Lodge Motel" neon sign. Use the sniper rifle and shoot the letters "L", "O", and "L" (in order) in the word "Lodge" on that sign. The message "LOL" will appear in the center of the screen to confirm correct entry. For a short period of time, any alien shot will explode into golden alien stuffed dolls.
