As you head out with Ishi to find Trishka, press RT to fire at the glowing gas tank to clear a path. When you arrive at the slope with the attacking gunners, kick the gas can toward them to blow them up.
Head across the makeshift bridge (a dinosaur's vertebra?) and up the dirt path. Use your leash on the Dropkit (the glowing pod) at the top of the hill to upload your Skillshot database. This will be used to help you buy weapons, ammo and upgrades.
Once you exit the database, kill all enemies on the other side of the gate. Log back in to the Dropkit, make any needed adjustments, then head through the lowered gate.
Head down the hill and kill all attacking enemies. Use your leash to hurl them into the cacti on the left side of the area for a bonus kill.
Once you reach the Refinery, use the red gas cans to your advantage. Take out the shooter on the platform by aiming at the red cans nearby him. Next, shoot the gas cans sitting on the hanging platforms to do some major damage.
Advance to the right side of the area and use your leash to access the Dropkit near the rock. Head through the main opening of the Refinery. Shoot the hanging gas cans over your enemies for easy kills.
Turn right and head up the stairs. Shoot the gas cans and continue across the catwalk. When you are prompted to, press and hold LT to map the complex.
Head down the stairs and kill the attacking enemies. Kick in the gate and press X to pull up on the lever and lower the lift.
