The Killzone series may be mired in darkness and a convoluted storyline, but one thing that always keeps me coming back to the games is their industrial design.
It has such amazing weapons, vehicles and technology. They look like they're from the future, sure, but they also look like they work, get dirty and break down, just like they do in the real world, a rarity in video game science fiction design.
These images, from Killzone 3, were done by Karakter, a concept art studio based in Germany and The Netherlands. They're mostly of some of the game's largest, most impressive installations and vehicles, though there's some environment art in there as well.
If you like what you see, the team's website also has examples of their work on games like Assassin's Creed II, Anno 1404 and BattleForge.
