Walkthrough

1
Hide behind the pillar on the right.
2
Look behind you and spot two gas canisters. Grab one and hurl it at Barrett using the fire button. This will stagger and injure him.
3
If you successfully hit Barrett with a gas canister, quickly rush to the other corner of the room and grab an explosive barrel.
4
Hurl the explosive barrel at Barrett for major damage.
5
Continue using the strategy of hiding behind pillars and using explosive barrels and gas cylinders found throughout the area.
6
If Barrett throws grenades, sprint to another pillar and look for a gas cylinder. After staggering him, hurl something explosive at him.
7
You can also use grenades or strategically placed mines. If you have detonatable explosives, hurl them at Barrett or a place you know he will pass by and time the explosion.
8
If you have Typhoon, use it now.
9
Barrett cannot be tranquilized; he is a mandatory target you must kill.
10
If you run out of options, grab a weapon and shoot Barrett repeatedly until he dies.
11
If you have the Stun Gun, try to stun Barrett. Successfully doing so will stagger him for a long time.
12
An alternative method is to get the Recoil Compensation augmentations 1 & 2. Start the battle by throwing a Gas Grenade at Barrett, then hide behind the concrete block. As he chokes, use a Machine Pistol or Combat Rifle and aim at his head.

Tips

Watch your health. Do not come too close to Barrett, as his melee attack causes 80 points of damage. Use painkillers when hurt.
Barrett can't be tranquilized; he must be killed.
The Recoil Compensation augmentations 1 & 2 are an alternative if you can't beat Barrett, but they are not as good as some other augmentations.
