As detailed in a Take-Two earnings report last night, the Murder on Eridanos expansion will be released for PlayStation 4, Xbox One and PC by the end of the current fiscal year, which ends on 31st March (via SeekingAlpha). Murder on Eridanos is the second of two DLCs for The Outer Worlds’ £19.99 expansion pass, the first being Peril on Gorgon - which launched back in September last year.
Very little is known about the second expansion, other than it being “Halycon Helen’s final and finest adventure,” so perhaps it’s something of a murder mystery. Peril on Gorgon raised the level cap to 33, along with adding new perks, flaws, armour sets and science weapons, so it’s possible we could see similar additions and another level cap raise in Murder on Eridanos.
