The reward for completing this mission is $100,000. The mission "Love of Money" is also unlocked.
Damn, it's a slaughter. Poor Cisco, you just wanted to sell your drugs in peace and retire with millions in the bank. So much for keeping your carpet clean, my friend. 8-Ball told me not to go vigilante on the world but now I'm taking the gloves off. Anybody and everybody that gets in my way is going down.
Mike, don't do this! You take me out and every two-bit thug with an eye for quick cash will still come after you! You think you can get away with my money? You'll be dead before you reach the city limits.
