Compared to Battlefield: Bad Company 2, Battlefield 3 will have more than 10 times the hardware unlocks spread over weapons, weapons attachments, gadgets, and a huge unlock tree for vehicles alone.The ultimate bragging right would be for a player to be awarded the rank of Colonel with 100 Service Stars attached, and to have 100 stars in all weapons, kits, and vehicles. Getting there will be a massive task – consider that a challenge!
The design philosophy behind the unlocks in Battlefield 3 is pretty sweet. We basically give you more hardware to play with for doing what you love to do. Case in point: Using gun X will give you more upgrades specifically for that gun. Playing with a kit and vehicle earns more upgrades for that kit and that vehicle. In addition, all XP gained also goes towards your overall rank, which in turn unlocks new weapons, specializations, and camouflages usable by any class.
Tactical unlocks force you to choose the right loadout for you
That’s the way all of the unlocks and upgrades work. They are specifically designed to be tactical in nature, forcing you to choose loadout based on the map and situation. Do you go for the heavy barrel for your assault rifle? It gives added accuracy for single shots, but at the cost of stronger recoil in burst fire/full auto mode. A standard assault rifle can be modified into a long range accurate weapon or for close quarter, almost SMG-like, combat. For jets, do you go with Maverick ATG missiles to take out tanks or AA missiles to dogfight airborne threats? With your Engineer, do you bring your anti-tank or your anti-air RPG launcher?
