Bosses are battles in which multiple players can attack the same target. These battles usually last multiple days in which the players spend their stamina to attack the bosses. Killing a boss rewards the player with many pieces of awesome loot, depending on how many 'points' you earn. There are also a number of Achievements that can be earned by killing bosses.
The bosses can be accessed by tapping on the stamina icon and selecting one of the boss options; boss list or summon boss. Once in the bosses screen, the 'Yours' tab shows any bosses that you are currently taking part in. The 'Public' tab shows other players bosses which you can join. Finally, the 'Create' tab shows a list of all the bosses that you can summon.
Each boss requires a certain item in order to summon them for battle. Some require a cell phone which you obtain by completing the last job in certain areas. While others require items that you obtain through the tech lab. Currently all of the materials required to create the items from the tech lab are obtained as gifts from other players.
Most boss battles have a number of stages, with one or more foes in each stage. Each foe has a class (see below). You can choose which enemy to attack, how much stamina to spend and whether to use a normal attack or the special attack from your class. The enemy will do damage to one of the people attacking it if it survives your attack. Once an enemy is down to a certain level of health, you will have the option to execute them.
The following lieutenants have powers that specifically affect boss fights:
When you join a battle, you choose your class for that battle. Each foe you meet also has a class. Certain classes do additional damage when they use their class-specific attack against certain other classes:
- Enforcers do extra damage against assassins.
- Assassins do extra damage against heavy weapons.
- Heavy Weapons do extra damage against snipers.
- Snipers do extra damage against enforcers.
