Campaign

When starting the game you have only one mode unlocked — Campaign. This main mode introduces new locations and enemies, and increases your loot level and overall difficulty.

There are 7 worlds in the game’s main campaign: City, Office, Forest, Train station, Desert, Laboratory, and Casino. Each world has a certain number of areas, which increases by one with each new world. Thus, the City has 2 areas and the Casino has 8. Every area contains 6 levels with up to 3 stages inside each of them. The 6th level is always a Boss fight. After completing all Worlds a player unlocks Episodes with 3 areas and 6 levels each. Currently, there are 14 Episodes in the game.

Levels always resemble the World style. In Campaign, enemies are stylized to match the World theme, in other game modes they are randomized. Levels are always different in size and amount of enemies, with new enemies being introduced gradually over time.

Each level of each World or Episode has a recommended Combat Power (CP), alongside different loot and item levels.

Levels start with the agent starting at the bottom of the map and end when the elevator at the top of the map is reached. There are various enemies spread out across the area within which the player has to defeat them to unlock the elevator. Until you make the first move, the agent won’t react to enemies around and those won’t see the agent respectively. When all enemies are killed, the player should reach and use the elevator to go to the next level. In Operations, the last stage will be completed only when mobs are dead and the loot crate is opened.

Progressing farther in the Campaign you get a higher enemy level that increases the difficulty for all modes in the Missions tab and increases the item (Weapon) level.

 Max item LVL

Finishing a level in Campaign grants a Normal Chest, Elite Pass experience, and Player experience. The amount of XP is displayed in the level info window accessible via the question mark sign. There you can also see the highest weapon rarity possible to drop in the particular Campaign level. With a higher Loot level, you get a slightly increased amount of regular rewards — Cash, Weapon Scrap, etc.

## Bosses

At first, you meet Bosses at the end of each area in the Campaign. Progressing through the main mode you find new bosses, which later will be seen in Expeditions on floors 3, 7, 11, and 15, also in Rifts and Hell modes. It is worth noting that bosses in Rifts are the same for every player on every floor each season, and you might face some boss that wasn’t yet discovered in the Campaign. If that boss wasn’t found in the Campaign yet, you won’t face them in Expeditions until they will be passed in the Campaign.

Bosses can have several different names in different game modes. They are a bigger version of similar enemies and have the same basic attack plus a special boss attack. Additionally, each boss can have up to 5 affixes that make them more difficult to defeat:
