Complete the following achievements to unlock Xbox Live Gamerscore points.
This can be accomplished at the beginning of the game, when you receive the "Bambam Club" mission. Once there, you will fight some punks. Grab one of them and smash him into one of the aquariums in the walls. The water will start gushing and a fish will appear. Pick up the fish from the ground and kill someone with it. To ensure that you succeed, aim for a target, hit him a few times with normal attacks to weaken him, then use the fish to finish him off. The killing blow must e with the fish. If this is not done, the fish may be destroyed before you have a chance to kill someone with it.
After reaching Face level 10 you will be granted a DAI LO 40% discount when you purchase cars and clothes. There are also clothes that grant about a 15% bounce discount for vehicles but they may not stack with the Face level 10 discount. There are four vehicle stores you need to purchase from, two in North Point, one in Kennedy Town, and one in Central. About $3.5 million total will be required for the purchases. To earn large sums money, call Tran for missions. He will ask you to get him cars, with some of them worth over $500,000.
Save the game, then bet at least 50,000 on any cockfight and win. If you lose, reload the game and try again. The best place to try this is Kennedy Town, as it features a minimum bet of 50,000 and is the fastest cockfighting arena to reach from your apartment.
