1 week later a lot of testing... I put all these crazy stuff into Sandbox+
linking to Missions, Triggers at the fun.
It's comes with loaded of 32/35 missions on start but one you complete it one of them, you won't able to do it again but reload your saves.
Even you beat the game, all missions...
You will see few peds are enemies, enemy biker and punks, and the construction worker, will kill you, that show's how bad is this city than Stilwater.
Note: There are unknown enemies that walks strangely in the streets.
