Those are custom suit skins I believe. They don't look that way by default. That's just for show.
I wasn't just talking about that screenshot in particular. I don't like the overall art style of the game.
I don't mind a cartoony look if it's done right (Team Fortress 2, Windwaker, Borderlands etc.). But it looks silly in this game. I actually think the upcoming XCOM shooter by 2K Marin, that everybody is hating on, has a way more interesting art style
Anyway.. I might end up buying it at some point, what I've heard about the gameplay sounds awesome.
