Grand Theft Auto: San Andreas - Madd Dogg
A ‘D' symbol will appear on your radar following the completion of the “The Meat Business” mission in Rosenberg's mission line. Make your way to the red marker outside of the Royal Casino on the Strip and step into it to get started.
Mission 1: Madd Dogg
Madd Dogg's rapping career is down in the dumps, which is mostly your doing. Madd Dogg is threatening to leap from the roof of the Royal Casino and into the streets below to end his life. You must quickly find some way to save him. Jack the pickup truck that's parked nearby and drive into the red marker in the middle of the crowd that has gathered. Now you must catch Madd Dogg in the back of the pickup after he jumps. This is a simple enough task, just try your best to keep the back of the pickup aligned with Madd Dogg's position on the roof, adjusting accordingly as he falls in order to catch him.
With Madd Dogg in tow, start toward the hospital in Redsands East. You'll have to drive carefully to ensure Madd Dogg's survival, as each collision will knock off a piece of his health bar. You have plenty of time to make it to the hospital before he expires, so there's no need to rush. Drive into the red marker outside of the hospital to complete the mission.
