hi people. u may know me from the tips i put on runescape.well this time i'm here to tell u how to get a rocket launcher in the level FINDING HARISHIMAS GOLD. when you eventually find the temple go in side and folow the paths untill u see a huge statue and there will be 2 guys standing on it. look to ur left and u'll see about 4 boxes. brake the and BOOM u got a rocket launcher. i think this code goes well with the invinceibility code(bengal) and infinet bullets/rockets/grenades(discus). but it's even better if u have the cheat snipe-o-rama(leleupi)on too.have fun killing japaneese lol see ya p.s look at my runescape hints to see how good i am lol.urik out.
