Respawn is currently working on Cross-play for Apex Legends, but is not promising anything at the moment.
Lead Producer at Respawn, Drew McCoy, told Eurogamer that it, “plans to allow players to play with their friends on other platforms,” in the future.
However, McCoy said cross-progression and cross-purchases will never be a possibility in the game. The inability is due to the way the systems were created early on in the process, which, “can’t
reconciled after the fact,” he said.
Apex Legends has already made a huge impact in the battle royale world, first with its secrecy around the game and its sudden launch on Monday. As of Tuesday morning, Respawn’s CEO, Vince Zampella, announced that Apex Legends brought in 1 million players in less than eight hours from its launch.
