Promethium

Complete Missions in Metropolis to obtain this rare Resource that allows use of Portals to an Elseworld.

Portals

Portals in Metropolis mark entry points to missions on Brainiac’s Elseworlds. Travel through them costs Promethium.

Incursion Missions

Incursions are high-risk, high-reward Missions that take place on an Elseworld.

Mayhem Missions

Take the fight directly to Brainiac in large-scale Incursions containing multiple Missions on an Elseworld.

Mastery Levels

Increasing the Mastery Level before traveling to an Elseworld raises the danger, but also the available rewards.

Extreme Weather

Depending on the Mastery Level of the Elseworld, you may experience Extreme Weather effects.

Enemy Ranks

The higher the Rank, the more deadly enemies become. Rank increases are applied to all Grunts or Brutes on an Elseworld.

Mutators

Brainiac deploys Mutators on Elseworlds to add gameplay-altering effects to enemies, changing the flow of combat. The higher the Mastery Level, the more Mutators will be active.

Deadly Terrain

Above certain Mastery Levels, some Terrain on Elseworlds will damage you on contact. Stay elevated or airborne to avoid it.

Promethium Timer

A time-limited Promethium Shield encases Missions on Elseworlds. When the timer runs out, you will be exposed to the full effects of Brainiac’s attacks.

Facilities

LuthorCorp technologies phased onto Elseworlds by Lex-2. Destroying a Facility provides temporary buffs to the entire Squad. Timed Facilities are only active for a limited period after entering an Incursion mission, so prioritize using them first. Brute enemies can also drop Timed Facilities on death in some missions.
