It's A Game For Team Players
No matter what type of game you're playing in Spec Ops multiplayer, the team are almost always four-on-four. (There's free-for-all deathmatch without teams.) Battlefield can keep its massive offensives, this is two squads squaring off in a battle for supremacy and bragging rights.
This is a game you're going to want to team up with friends for. Unlike other team-based shooters, it's essential to stick together and co-ordinate with your squadmates. Each class adds a different kind stat buff to all allies in their immediate vicinity, so even your team doesn't have chemistry, you're stronger together than you are apart.
A team of four lone wolves are going to have trouble winning matches, even if each of them is better than every one of their opponents.
