I have always viewed Killzone as Sony's counter to Halo. They are both science fiction first-person shooters, though Halo has always been regarded as the better of the two by a fairly comfortable margin. I never really go into the Killzone series. I know there have been games from the series on PlayStations 2 and 3, as well as the PSP and Vita. I even went so far as to pick up the HD collection on PS3 several months ago really cheap, though I have not really had a chance to settle down and play it much. I have poked at all three campaigns at one point or another, and I also spent some time with the online. Generally the titles were enjoyable, but they never really hooked me.
