Serious Sam Cheats
Get the Heart Without Getting Caught!
Entry Location:
OK. First, go to the Tomb of Ramses III, then, later on in the level, there is a cage with a heart inside. Get in line with the heart, or one of the four entrances. Push up on the joystick as hard as you can to get to the heart inside the cage. As soon as you get the heart (you'll need reflexes for this part) back out as fast as possible. Then, instead of being caught in the cage, you will be free!
