Completion of the series of games (three in all) will provide the player with three Unlock points, used in Killzone 3 to unlock guns or abilities in the multiplayer. You can take a look at the gameplay for the minigame on the official PlayStation Blog.Those who might pre-order their copy through Home will also get a few extra bonuses that aren’t just limited to the jetpack, including:

Retro Map Pack, featuring two of the most popular maps from Killzone 2.

Utilizing Home in this way is definitely a better way to ensure that people might start checking it out more, especially if it allows them to unlock things faster. The concept of Home is interesting, but it has never really been something that has been truly impressive as a feature. Maybe that will start turning around with Total Game Integration?

Killzone 3 will be coming exclusively to PlayStation 3 on February 22, 2011.
