Beating Gurgolon
To beat Gurgolon (the giangantic beast in Raiden's last variety level [get variety by completing sneak, weapons, and first person modes] and perhaps in a few other levels) use your stinger to hit one of his targets. Afterwards, pull out an Ak47-U and shoot the little blue thing swarming around where you shot him. The target will get smaller and smaller, making it more difficult to hit. Eventually you will destroy the target. Pull out your stinger and again hit another of his targets, pull out the Ak47-U and shoot. Just repeat this until all targets are blown out. Also, there is a funny little thing you can do. Put on a BDU (enemy body guard outfit) and equip an Ak47-U. Let the beast trap you in place with his soundwave then let me fire his eyebeams. Before it hits you, an explanation point pops above his head, which changes into a heart. He picks Raiden up and walks off with him as love music plays.. the only drawback is that you lose the mission.
