"When you drop your game out of nowhere and 25 million people show up in the first week, there’s going to be all kinds of issues, bugs, exploits, etc. discovered." And so goes the fairly transparent post made by Respawn over at the Apex Legends subreddit. Adding that stability and performance is a key issue that will be addressed in upcoming patches.
And speaking of which a new patch is set to drop this week. The post goes into detail about how the team is managing player issues - which no doubt is a monumental task with so many players. As there currently isn't an in-game reporting tool in Apex Legends, the post all but notes that one will definitely be coming in the future.
Report tool or no, Respawn notes that over 16,000 cheaters have been identified and banned from the game - with Respawn planning to check-in daily with the community via posts keep them updated on all things Apex Legends.
