Easy Solo HUV EXP Guide in CRAS
1) Go to Station 1 in Cras. Use it so that when you reset, you respawn there.
2) There should be a series of 3 Trees and poles then an empty space then another series of 3 Trees and poles. Park there and wait for HUV call.
3) HUV should spawn in Cras Seaside Apartment 1st Complex. If it didn't, you've failed. As you can see from the map, its a long straightaway. 99.9% of the time, the HUVs will turn left then turn another left going giving you another long straight away. I usually kill 3-4 before they turn though.
They spawn here:
4) Once you finish killing them, press escape and go to Server selection
5) You will end up in the Driver Dome, Reverse and choose Channel 1.
6) Right away you'll get a call for another HUV chase, drive to the spot again before accepting.
7) Rinse and repeat
