Killzone 3 had about as traditional a video game release as you'll see these days: a $60 boxed copy including a short single-player campaign and in-depth multiplayer modes, with the latter serving as the main attraction for the majority of hardcore fans. Sony's moving away from that next Tuesday, though, by offering a free version of the game's multiplayer for download. It'll be fully-featured except for limits on unlockable items and an as yet unspecified level cap, which can both be removed by paying $14.99. The model is similar to that of many free MMOs that seek to hook players before they lay down any money. Killzone 3, on the other hand, is a banner title for the PlayStation 3 and just hit its one-year anniversary — giving players the option of trying it for free before paying a lower price for the most popular mode sounds like a smart idea.
