As part of their The Road to Battlefield 4 series on their site DICE developers talked about the development of the multiplayer classes. The four classes are Assault, Recon, Engineer and Support. They may be familiar to any fans of Battlefield 3, but all the classes have been “tweaked to be more versatile and more highly specialized within their field.”
The Engineer was granted a lot more variation in anti-vehicle weapons to give him a broader set of tactics from the high damage yet challenging to use RPG-7V2 to the “fire-and-forget” with low damage smart weapons like the MBT LAW. Fan favorite Wire Guided Engineer Missile from Battlefield 2 also makes its return.
The Support class has been given a few more offensive options. Such as the XM25 for some indirect suppressive fire or a redesigned remote mortar for an indirect assault. He also gained the ability to equip carbines and DMRs alongside his usual C4 and Claymores gives him added range in combat roles.
The Recon has gotten a boost to his mobility as well as the return of his “Spec Ops play style” from Battlefield 2. For fans of sniping, the mechanics have been revamped with a rebalancing of the Sniper Rifles. You now have the ability to zero your sight to set an aiming distance. It also comes with additional optics and accessories.
The Assault is still the “frontline run-and-gun kit” and combat medic in a pinch. The developers have continued to have him be the go-to class for med kits and defibrillators. They added more versatility to him with the First Aid Pack, which heals a single soldier over time, and 40mm Flash Bang round to clear a room fast.
The developers at DICE hope that these changes and others allow players to “explore a wide range of combat roles and sub-roles when picking your load out and kit.”
