GTA San Andreas - Supply Lines in 10 Seconds
Updated run from my 2:12, absolutely decimating my previous time due to the exploit of undespawnable vehicles.
Special thanks to Rhans' video on marking vehicles • How to mark multiple vehicles. . Due to this new exploit by duping Explosive Situation I was able to keep 6 vehicles spawned in at once across the San Fierro area without the mission despawning them.
From trial and error I learned the approximate starting positions of the five targets. By placing 3 tanks in specific spots I was able to almost instantaneously destroy the 3 van targets as they spawn inside the tanks which causes them to violently merge inside of each other doing insane amounts of collision damage.
As for the other 2 targets the collision method didn't work as the bicycle is immune to damage and the sanchez barely takes any damage when stuck inside of a tank. To get around this I duplicated the mission 3 separate times to acquire 3 remotely controlled barons. Though the barons are able to avoid being despawned by the mission, they will fall through the ground if you are too far away from them which is why I placed them on the Dft truck and Windsor.
As I started the mission I immediately fired the baron which fires all the stationary barons and kills the bike targets, at the same time the van targets are destroyed by the tanks. Funnily enough the game doesn't allow you to finish until you've heard all of Zeros lines which is why I had to pause buffer the ending lines. Unfortunately I had to wait in the end marker a couple of secs as the bicycle target jumps off his bike and takes a while for the barons to kill him and for the mission to acknowledge his death.
