Shadowfall was incredibly disappointing for me, Killzone 2 and 3 were easily two of my favorite exclusive PS3 games. Only Sony franchise I'd have ranked above it last gen was Uncharted. It was the 1 exclusive I was most excited about before launch on both PS4 and X1, and it ended up being the launch game I was most disappointed in.
SF was KZ4 essentially. Just took place like 30 years after 3. Even review sites were calling it Killzone 4: Shadow Fall.Pff Killzone 4 1st.
I liked Killzone: SF but i was definitely more of a KZ2 and KZ3 fan. Especially KZ2, that game was so epic. The controls just needed to be better.
KZ2 was my favorite last gen FPS. It's a shame, but I think GG lost their magic over the years.
