Part 1: Infestation
Even before the Exodus, Roswell, New Mexico was a place of mystery and conspiracy. Now its legend has grown stronger. Whatever the pre-Exodus military was hiding there, it’s important. Important enough that some people would do just about anything to get their hands on it. Infestation is an Exodus OPS campaign scenario for 4 to 6 characters of 4th to 6th level. This adventure directly precedes Submerged, and should be played immediately before it.
Part 2: Submerged
A pre-Exodus device has brought you to a strange underwater settlement inhabited by inhuman creatures. Where are you? What is going on? And, more importantly, how will you return home? Submerged is an Exodus OPS campaign scenario for 4 to 6 characters of 4th to 6th level. This adventure directly follows Infestation and should be played immediately after.
