Grand Theft Auto III/Farewell 'Chunky' Lee Chong

Brief
"Chunky" is selling SPANK in Chinatown with his noodle stand as a front. Joey wants Claude to go and take him out.

Walkthrough
This mission has many solutions.

Nothing But Flats
For all of these methods, popping the tires of both his Perenniels is a good idea as this makes his getaway cars virtually useless. Just drive around the block until you've spotted both of them.

Nowhere to Run
Take the Perenniels and dump them in the ocean, or blow them up, or whatever. Chunky will then have to escape on foot, meaning you can catch the fat fool effortlessly.

Sniper Rifle
Get a sniper rifle (from collecting enough Hidden Packages). Go to the southern entrance and give Chunky a headache he'll never forget.

Carbomb
Take one or both of Chunky's Perenniels to 8-Ball's bomb shop. Arm the bomb and get out. If you only used one bomb destroy the other car or dump it in the sea or something. Chunky will always run to the nearest car.

When he starts the engine, BOOM! (The Definitive Edition will give you an achievement for using this method!)

Molotovs
Go to the tunnel behind 8-Ball's bomb shop, you can also access this from behind Supa Save. In there are some tramps drinking bottles that upon closer inspection turn out to be molotov cocktails. Run them down and you should get four molotovs. Drive back and throw them in Chunky's general direction, they've got enough spread that your aim can be terrible and you'll still roast him.

Driveby
Stock up on Uzi ammo, probably from Hidden Packages. Then ride your PCJ between the posts, shooting as you go. If you don't hit him with your bullets or your bike he might make it to his car, so just fill it full of lead. Simple. Just don't drive so slowly that the Triads are able to knock you off your bike and you'll be fine.
