Valentine's Day Massacre adds a new weapon, vehicle, clothes and 10 new jobs. The Gusenberg Sweeper machine gun will be available at the Ammu-Nation store in Online and automatically deposited into inventories in Story Mode. The new vehicle, the Albany Roosevelt, is an armored 1920s limo available in any garage in Story Mode and from the Legendary Motorsport in-game website in Online. New attire is flapper-themed, and new jobs include Deathmatches, a new Parachute Jump and new Races.
And yes, "brakes" is spelled that way on purpose.
