Kill Yourself:
     Press  R1,  R2,  L2, R1, R1, R1, R2, L2, L1, L1 then press Square
quickly.  Your  player  should  blow up and say, "What did you do that
for?"

Hints:

     Take careful aim and go for head shots when you can.

     Don't forget that grenades can do the trick when firearms can't.

     A  stealthy approach is best. Remember, you have a huge advantage
if you see the enemy first.
