This might have already been addressed somewhere else in this thread, but unfortunately I don't really have the time to go trawling through 68 pages of posts!

Is there anywhere that I can download the Pulse DLC packs for free? I can see only three on the PSN (I've heard there are four altogether) and I know this might seem like a really tight fisted thing to contemplate, but I just can't justify spending over £10 on DLC packs when I've only spent £5 on the game.
