Weeeeeeeeeiiiiird game mechanic ....
Soldier's biggest innovation is the new link-up system, which can be used in co-op and online multiplayer. It allows you to share abilities with teammates standing next to you on the battlefield. Link-up can be activated by pressing a single button, which gives control of your player to one of your teammates, making him or her the squad leader. Your character will then automatically follow the squad leader across the battlefield. You are only required to use the look stick to aim your gun and take out enemies, allowing you to provide cover to the rear without having to worry about losing sight of the squad leader. Less-experienced players can link up with veterans to learn the layout of maps, with the more-experienced player providing cover and guidance over voice chat. Veterans will also benefit, as abilities are magnified when linked with other players. For example, the optical camouflage of one player can be shared with others in the group, increasing its duration and giving it to players who do not have it equipped. Link-up is also beneficial to engineers, who can then pilot drones without losing the rest of the group.
