It seems that Sony is feeling quite generous. Next week gamers will be able to download the multiplayer section of Killzone 3 without having to buy the game itself. The standalone multiplayer mode will be released as a free download on the PSN.
This mode will be launching on Tuesday and the only negative is that players can play for free up until a certain unreleased level cap. If a player hits that level cap and still wants to level up further they can pay $14.99 to unlock the full multiplayer experience. However it is worth noting that you can still continue to play for free, though you won’t be able to level beyond that cap without paying extra.
