The original Titanfall skipped EA Access when it launched with the terms for the subscription service clearly stating that the game would not be included. It is no surprise that the same shenanigans will occur with the sequel as the EA Access TOS have now been changed and include the line “CONDITIONS, LIMITATIONS AND EXCLUSIONS APPLY. EXCLUDES TITANFALL 2”
That means no early access on EA Access, or indeed Origin Access as the game is also coming to PC. Perhaps Respawn have some sort of deal with EA to keep the game off the service for a year as Titanfall did finally arrive on the service exactly one year after it was released.
