This campaign is primarily a result of feedback on the previous campaign. It adds stuff that was brought up while expanding on what is established.

This is most noticable with the inclusion of Dr. Malroy as a boss and a conclusive end to the story arc. I debated heavily on including Dr. Malroy since unique bosses can make or break campaigns, and opt'ed to leave him in. Both because I think it's fairly well rounded and it closes his story arc properly. (You don't get that 'yes, we killed that bastard!' feeling if you don't directly interact with him)

Emphasis was put on stuff that wasn't a focal point previously. There's plenty of different environments this time and the portal element is used more often. There's also more randomized stuff in each map and optional things to do.

Additionally there's 3 possible exit scenarios. These aren't dynamic like last time though, these exit scenes affect the outcome of the entire campaign differently.
