KILLZONE 2 map pack bundle

So i bought a slim on launch and also purchased killzone 2. I have been really enjoying the online play and was wondering if the map packs are good or is this another modern warfare situation.

I bought the first two (Cruiser and Train) and second two (Beach and Southern Hills). The second two are meh-ish, but Southern Hills is a good level. I haven't bothered buying the third one and probably won't for a while so I can't comment on it.

To answer your question, Cruiser and Train are definitely worth it 'cause the Train level rocks so hard (so get it for sure). If I hadn't bought two out of the three, I would just get the bundle with all of them though.
