How do you finish dildo dodo mission in a easy way?

The best way to finish the Dildo Dodo mission in an easy way is to watch for the snipers on the hills. They pick you off easily, so make sure you navigate the canyon carefully, ducking behind abandoned buildings and obstacles to avoid fire. This can be tricky, so be sure to save often. Once you make it around the bend the sniper fire will cease but you will be face with three ninja assassins, who are tough to shoot. Best to switch to third person here and use your katana. Once they have been finished one of them will drop a key you need to open the gate ahead. Once through there will be a short cut scene and the Dildo Dodo will erupt from the ground and begin chasing you around the volcano. If you happen to have any grenades on you at the moment, use them, otherwise, avoid the Dildo Dodo til it crashes into the wall and gets stuck, then shoot at it with your Uzi. You will need to do this several times. Soon the Dildo Dodo will let out a shriek of pain. There will be a short cut scene where Nepis shows up and aids you in blowing up the Dildo Dodo. Mission accomplished.
