Massive Killzone 2 Image Comparison: 2007 vs 2008 vs 2009

Gamezine:

"An aesthetic insight into the progression of a video game's development.

It's not often that you get to see a game three years in a row. With Killzone 2 we were "lucky" enough to have a glimpse in 2005 in the form of a CGI trailer.

There have been plenty of comparisons showing how close the actual game's graphics are to that trailer, but what about a comparison of the game's engine from early 2007 to its final 2009 build, via 2008?

Lots of improvements across the board, many you'll be unable to spot in this comparison, but you will notice shallow differences and huge improvements, especially when comparing 2009 to 2007."
