Electronic Arts has announced a new variant for the "On the House" initiative, this time dedicated to expansion packs and DLC. The concept is the same as with full games, which means that EA will offer a payed DLC or expansion pack per month to all Origin users. The expansion currently being offered is Second Assault, from Battlefield 4, and players can now download it for free.
It should be noted that you still need to own Battlefield 4 to enjoy Second Assault. Despite the new expansion pack offer, EA is still giving away free games, and this month's offer is Nox, completely free for Origin members. You can check both offers right here.
