All the locales look authentic, as each level is pretty different from the last. The levels aren't the only things looking good, either. The models in SoF are amazing. When I first heard about this game, I thought it was going to be boring. I was pleasantly surprised.
Every model is detailed and varied.
On top of that, the enemies change drastically from place to place. Arctic soldiers in Siberia, shirtless gangsters in New York, and military soldiers in Iraq. Glasses, hats, eyes, noses, and skin tone can all be interchanged, making for a staggering variety in enemies. That means not only are the gunfights fast paced because of good level design and instant-hit weapons, they're also dynamic and interesting every time, because it's always slightly different. SoF is not without its faults, however.
