If you want to play Titanfall on PC, you will need to have Origin installed.
A fan asked Respawn Entertainment’s Vincent Zampella on twitter if Titanfall needed Origin and if the game would be available on Steam. Zampella replied “yes it does”.
It’s also worth noting that you will need Origin to participate in the upcoming Titanfall beta too. The beta is free as you don’t have to pre-order the game to play it.
Long story short, make sure you have Origin or else you cannot play Titanfall on your PC.
