Siren's Call

Siren's Call is an area added in the Skills 2.0 update, being located on Petrichor V. The stage is apart of the fourth set of Environments in Risk of Rain 2.

It features what appears to be long-abandoned ancient technologies stuck in a Titanic Plains-esque landscape.

This is the only area where the Alloy Worship Unit, a stronger variant of the Solus Control Unit, can be found in.
