If there are no cards left in your draw pile, you are Suffocating.
Hunter Killer is a 1v1 competitive card game based on submarine combat. The design ethos is that information is both danger and opportunity, and the game is designed to simulate the suspense of a real underwater battle.
I designed the initial rules for Hunter Killer in 2016. Since then, it has undergone playtesting and several rules revisions. I don’t consider it finished, and plan to someday come back and polish it into a Kickstartable product.
