Ahead of the start of Apex Legends Legacy, Respawn released Northstar, a brand-new trailer that showcased the upcoming season's playable character: Kairi "Valkyrie" Imahara. And sticking with the theme of "legacy," the Northstar trailer contains several references to the rest of the Titanfall universe.In the video above, Jordan Ramée details all of the Easter eggs and references that we've managed to find in the trailer. Some are rather obvious, like the appearance of Blisk and Rampart. Others, however, are a bit more subtle, like the appearance of several Apex Predators prior to the Battle of Typhon.Alongside the addition of Valkyrie, Legacy will also introduce a brand-new bow weapon and Olympus map overhaul. The bow, called the Bocek Bow, will be a new mid-range option for Respawn's battle royale. Meanwhile, the pristine look of Olympus will be replaced with an infested metropolis that's filled with plantlife.Apex Legends Legacy is scheduled to begin May 4.
