Titanfall will be free to download and play for 48 hours this weekend as part of Origin's new Game Time service. Unlike Steam's Free Weekend program, Origin is making select games free for a set period of time that starts once you begin playing.
Just to note, that's real-time rather than game time, so the free mech-mashing ends after 48 of your Earth hours. EA also says progress during free access is saved, so if you choose to purchase the game afterward you can pick up where you left off.
Game Time is the latest of a few recent initiatives to bolster Origin. EA introduced On the House to the portal earlier this year, with the service offering permanent freebies that have included Peggle, Dead Space, Battlefield 3 and Plants vs. Zombies.
