Why there are so much Cubans?

Tommy starts with a rampage mission, riding on a pickup truck and taking down 55 Diaz gang members in just two minutes. After finishing, he calls a taxi to Little Havana, grabs some food, then heads to a pharmacy to pick up medicine. From there, he meets Hilary at his garage, where Hilary shows off a newly modified car. They go for a drive together, but soon the cops chase them for speeding. Tommy and Hilary split up, each escaping in their own way. Tommy continues toward Prawn Island to meet the Sharks. On the way, he discovers a hidden garage. A Haitian man with a strange headdress comes out, but Tommy quickly destroys him and moves on. At the Sharks’ mansion, the gang is preparing to raid their downtown base, which the Cubans had captured earlier. Suddenly, the cops storm Prawn Island. Tommy fights alongside the Sharks to push them back. Once the situation is under control, they launch a surprise attack downtown and successfully take back their stolen base from the Cubans.
