Follow the Weapon Glitch

Follow the Weapon Glitch...

Those weapons that can normally not be followed by holding in R2, can be followed with the Weapon Glitch.
Meaning rails, bombs, rockets and plasmas can be followed by this Weapon Glitch.

How to do it:
In Mayan jump down into the lava, press R2 button while jumping down into the lava, keep pressing until you die and X appears.
Keep pressing X until car respawns and you will see fire behind your car, meaning you can now follow all weapons.
