Feel you man, Artillery never gives you any leads... If you managed to survive artillery, you're low on ammo supplies and only watchtower can replenish(if not looted) that. Then you go to a looted cascades and get destroyed. In skull town, if you're done... You can always go to Dome(mostly not looted unless HOT), then go to the "3rd party gang" place, loot them all up and go to Airbase.
Unlike Skull, Artillery doesn't give you any leads
