OCC published a review on the Star Control: Origins
A quote from the article:
The Earth Rising Expansion consists of four parts: Aftermath; Return of the Lexites; The Syndicate; and Earth Rises. As the title of the first part suggests, the main events for the expansion do take place after the campaign of the base game, but some content is available during it. For this reason I decided to completely replay Star Control: Origins so I could enjoy any missions, weapons, and ships added to the full experience by the DLC and accessible before truly beginning them. This does mean there are now two review playthroughs covering the base game uploaded, which is something I took advantage of actually. I am also writing the parts' sections of this review after completing the respective part, and thus do not know if any question or concern I may be left with is answered or resolved within the next part.Star Control: Origins Review
