Cold War is the het ship between Ethan Mars and Lauren Winter from the Heavy Rain fandom.
Ethan and Lauren have no interaction within the game and have never met each other.
Although there are no works on AO3 with this ship, and no tagged works for it on Fanfiction.net, there are two works that involve a budding romance between the two. It is the third most written ship for Ethan and tied with Shelter for the most written ship for Lauren. Fans of this ship often ship them because of their similarities; both of them lost a son, their significant others (Ethan's wife Grace and Lauren's husband Allan) left them afterward, and both are determined to find the Origami Killer.
- Their ship name comes from their last names; Winter is associated with cold; Mars means war.
