Current game version:

Jovian Radiation is an optional Campaign mechanic which irradiates Europa over time. It travels in an extremely slow wave starting from the left.


The radioactive area grows slowly from the left side of the map, based on time elapsed in game. It appears 5 rounds after the start of the campaign and advances by 0.5% of the map width per round, meaning it will cover the whole map in 205 rounds.

Once an Outpost is exposed to radiation for 10 rounds, it becomes an Abandoned Outpost.

A level which is affected by radiation has the following effects:

Target Effect
Humans Periodically inflicts small doses* of Affliction Radiation Sickness.png Radiation Sickness on all humans.
Regular Creatures Dead via Radiation Sickness
Mission Creatures Same as creatures.(inconsistent)

Radiation will not destroy the last 4 outposts in the map.



  • The Jovian Radiation was added in (Embrace the Abyss) . It is meant to prevent farming resources in low difficulty levels by forcing players to move forward.
