Grove Street and Ballas Shootout in Canyon for GTA San Andreas

The Ballas announced to the Groove-Streeters an arrow in the Canyon. You have two options — to help the brothers or to be a Straight Buster, as Ryder said — go to the Ballas side.
Fashion Features:
Reinforcements are coming to the Ballas and Groove-Streeters. It was similar in my other fashion.
There is a check on whether you are in the canyon or not. (Made so as not to load resources)
Epic! Feel yourself on the arrow on some SAMP or MTA server.
Version V2:
Now it's a mission
Code update, and optimization
Added a marker on the map, (green man) to find the mission.
A sphere has been added, if you step on it, the mission begins.
If all the ballas are killed, the script clears the remnants from the missions, which clears the memory.
Added 1 more ballas machine.
Correction of departures.
Mini cutscenes.
Pickups of health, armor (to get them, you have to be a real kamikaze) and pickups of different weapons at the entrance to the canyon.
Fixes, fixes, fixes...
