@Real5me Titanfall 2 is still available on EA Play (Origin). EA has been upgrading the editions of several EA-published games on EA Play (Origin), which has triggered messages about these EA games being removed, but in actuality it is the standard editions of these EA games which are being removed (because they are being replaced by higher editions), not the games in their entirety. Some games have been cycling out of EA Play after a period of two years, but these have been third-party games, not EA-published games.
If you are seeing notice of Titanfall 2's removal from EA Play (Origin), but you can still play the game via EA Play (Origin), disregard the notice. If you are having issues accessing Titanfall 2 via EA Play (Origin), check to see if you have already been upgraded to the Ultimate Edition (including the Deluxe Edition) content on the Extra Content tab on the game's details page in your library. If that content has not been unlocked, you should be able to upgrade to it. If it has already been unlocked, you might need to clear Origin's cache. If clearing Origin's cache doesn't resolve the issue, you might need to uninstall the game and remove it from your library, then readd it to your library and reinstall it.
