Press O and you will initiate ‘Lone warrior mode’ where the rest of the team will stay and hold the defensive formation and you break out trying to create holes and weaknesses in the enemies team/army, for your team to exploit. When ‘R3’ is pressed your team/army will join you in an All out attack (everyone will try take as many man down, NPC’s AI of your team will be programmed to target the weaknesses that you have created.)only use this when fighting armies/enemies that are small in numbers, less powerful and when your being overpowered resulting in you telling your team to resort to drastic measures, where defence is thrown out the window.
If is pressed you go back to Neutral; where your army will work as a team to fight against the enemy. NPC will fight without you commanding them, and you shall be controlling your player.
Depending on your team, the transition from Lone warrior to Ultra defensive could be executed perfectly...IF... your team has high stamina, team bond and each member has a good rank level. The maximum level your comrades can reach is level 15, through Training and continuous missions, war and fights, your team will go stronger “together increasing the team bond every time a battle is won and teamwork is. E.g. you could be a player who decides to keep ‘over’ using the Lone warrior mode, your will progress quicker than anybody else but your team will wont progress
