Cool but, theres easier, faster way to do this. Get a big enough vehicle, get top of the vehicle and go over the fence where the ramp is on the other side. You can keep your guns and just snipe the target from a distance.
so much work for nothing. Just use a car to get up from that 0:02 left cylinder place . If you have a bomb surely you have a sniper rifle 2. just go there as usual when he's in the car type big bang. bruh
