Hearing that the more open level design quickly regresses is probably the biggest disappointment for me. I've always felt Killzone, as a series, really isn't all that great (I don't think Killzone 2 is a good shooter at all, but Mercenaries does some great stuff), but the wider play space and open level structure had me more excited than I would be for a Killzone game.
same here. this is the specific critique that has me worried I wont get very far in the game. I hate strictly linear corridor shooters and was only excited about KZSF because they opened it up.
but if it's only open for half or less of the campaign. then ehhhhhhh
