It is possible. Here is what you must do:
1. Unplug everything on your PS3.
2. Put it in a microwave on high for 1 minute.
3. Take your PS3 out and smash it with a hammer 5 time.
4. Plug everything back into your PS3.
5. Put in the Halo disc and start the game.
6. If it still doesn't work repeat steps 1-5 until it works.
And that is how to play Halo on your PS3 without harming it in any danger.
I don't need to get a life. I'm a gamer. I have many lives.
