 The game also features a multiplayer mode , called Combat <unk> , where various players can compete against each other in different types of <unk> and objective @-@ based games . Aspects of each game can be highly customized . Features such as the weapons available , the winning condition , and team management can be changed to match player preference . Computer controlled <unk> , called Simulants , can also be added to the game and each of them can be individually customized , including their appearance , difficulty , and behavior . Players can also issue orders to the Simulants on their respective team ; for example , Guard tells a <unk> to stay in its current location and guard that area . The player can explore the Carrington Institute , which serves as the game 's training ground , and take part in different training activities . The most substantial of these activities is the shooting range , which allows the player to test all the weapons of the game against moving targets .
