Now, the next crossover promotion for Rockstar's big games has been announced, though unfortunately details are light at the moment. >In a May 8 blog post, Rockstar said fans can "look for another lost relic from the frontier to be unearthed in Los Santos later this year." Though this line never mentions Red Dead Redemption 2 by name, "the frontier" is a strong suggestion that it pertains to the upcoming open-world western game.
