Criterion has made the Legendary Cars DLC for Burnout Paradise free today in memory of Harold Ramis, who passed away on Monday.
The downloadable pack, originally released in February 2009, contains four cars based on famous movie and TV vehicles.
The cars featured include unofficial tribute versions of the KITT car from Knight Rider, the General Lee from The Dukes of Hazzard, and the DeLorean from Back to the Future.
However, the reason the pack has been made free is the fourth car, the Manhattan Spirit, which is based on the Ecto-1 car from Ghostbusters.
Ramis is best known for not only co-writing Ghostbusters with Dan Akroyd, but also starring in the movie as Egon Spengler. His death on Monday prompted Criterion to make the car downloadable for free.
"Harold Ramis was a comedy genius," the studio tweeted earlier today. "He inspired us. To honour this legend, #BurnoutParadise #LegendaryCars are free today for #Xbox360."
In 2009, Ramis lent his writing and acting talents to Ghostbusters: The Video Game, which he once again co-wrote with Akroyd and starred in as Egon.
The game was set two years after Ghostbusters II, with Manhattan once again overrun by ghosts and supernatural forces.
