 The game 's battle system is the series ' trademark Linear Motion Battle System ( <unk> ) , which places up to four playable characters on a 2D plain against enemies in real @-@ time combat similar to a beat ' em up . The version used in Destiny 2 is called the " Trust and Tactical <unk> " . When entering battle , the camera follows characters , <unk> in and out depending on their distance from an enemy . During battle , one character is controlled at any one time , with the others being governed by the game 's artificial intelligence ( AI ) : the AI can be customized to behave in various ways , such as adjusting their aggression level , and balancing magical and physical attacks . In addition to real @-@ time commands given in battle , the player can issue commands to all characters by pulling up the battle menu and issuing commands . A character 's performance in battle is governed by their current level of Spirit Points ( <unk> ) : the more <unk> a character has , the higher their defensive and offensive abilities . A character 's health is represented by Health Points ( HP ) . Three types of attack are available and activated progressively depending on the number of hits an enemy has taken : a standard attack , named attacks called <unk> , and special high @-@ damage attacks called Mystic <unk> . At the end of each battle , its performance is assessed an given a Grade , which can sometimes trigger a bonus such as learning new skills . Some bonuses are also carried over into the next playthrough . In addition to the single @-@ player functions , a local multiplayer option is available , supporting up to four players : when additional controllers with players are connected to the system , AI functions for selected characters are disabled , switching to manual control . An auto @-@ battle option , which has the game 's AI controlling all characters during a fight , is also available .
