Sixth, seventh, eight, missions released. Check the main post for the links. Watch/Play, enjoy, and give feedback (if you wish).
(The Father) mission was unlocked due to the fact of finding and using the hidden vehicle in the previous San Fierro Rifa mission. There is a hint in this mission.
(More Trusting Issues) mission contains seven note books (some containing helpfull information [hints] and others being less helpfull). There is also a decision available to complete at the end of the mission: burning or keeping the drugs field.

-Have you burnt the drugs field or did you preserve it?
(The Two Weak Mexican Gangs) mission contains one "challenge" and a decision making opportunity is made available for a future mission.
-How many Aztecas (enemies) vehicles were destroyed in the mission?
-About Jose's call: -will you go alone? -Will you go with the San Fierro Rifa? -Will you go with The Truth?
