Do you like Survivor the reality show?

I cant think of the name for a movie. group of prisoners on an island on a reality show like survivor. They fight for money and mutants.

• I saw it about 2-3 years ago. There's like 10-15 people who where criminals in prison for crimes such as computer hacking, murder, theft. They go on this deserted uncharted island, and are given, knives I believe. They are put on teams of two, and will search for a prize ranging either 1million to like 100 million I can't remember. They will also search for crates with supplies or weapons. On their journey they though there threat was the other competitors (who they fight and kill.) but later on, zombies are shown attacking the prisoners. It later reveals they were part of an experiment or something and are american soldiers. It ends up being this guy, and this girl, who basically slid past (unlike the guy who played strategical.) And The two people in there didn't have their partners, and they needed their partners to get the money or something. But the end up getting it together, and then the guy kills the girl. He drivers away on the boat with the money, and is attacked by the zombies in the boat. It was released in anywhere from 1996-2007 What is this movie?
