It's violent carnage and war. It's likely because of people like you that the Killzone franchise keeps getting watered down. Too much bloody hand holding required in gaming these days. Eurgh...
No kidding. I don't need my enemies in vibrant colors or anything else to stick out. Last time I checked, making the enemies blend in more IS part of gameplay if the devs want it that way. I'd love to see what people would bitch about if they tried to play a game like ArmA 2 then...lol. There's a reason GG put the red and blue lights in the game to be identifiers which is as simple as it can get.
But I guess we should say "fuck the developers" like the .gif poster just because it's not to his liking. No wonder developers have a hard time pleasing their old fans when they have to listen to shit like that...
