Square Enix has trademarked something called Lara Croft: Reflections, which is presumably the name for the upcoming sequel to the Tomb Raider reboot—if it isn't something else. This is the second time that the company has trademarked the name.
As far as we can tell, there are no plans for story-based DLC for Tomb Raider, so it's safe to say that Lara Croft: Reflections is something else entirely.
As we previously reported, the Tomb Raider comic book will tie in directly to the sequel. Whether that sequel will be titled Lara Croft: Reflections remains to be seen.
