Sony has announced that the multiplayer portions of Killzone 3 will be available as a free download on PSN.
PlayStation 3 owners will be able to access three game modes, all maps and DLC packs, and level up to the tenth rank: Sergeant.
Players can continue to progress through all 45 ranks, unlocking trophies and weapons, if they purchase the multiplayer portion of the game for $14.99, or buy the full game, which includes a single player campaign.
World of Warcraft offers a similar free-to-play structure, capping unpaid accounts at level 20.
Ars Technica reported that the company had announced other features over the PlayStation Blogcast, such as double experience events available only to paid accounts, and double experience for the first twenty-four hours after purchase.
The free download will be available on the 24th of February.
