The comic is written and scripted by BioWare lead writer Mac Walters, drawn by Eduardo Francisco, colored by Michael Atiyeh and letterer by Michael Heisler. According to Walters, Mass Effect: Incursion was created to flesh out a conversation between Liara T'Soni and Aria T'Loak in Mass Effect: Redemption: "We wanted to continue to explore the original comic book, Redemption, and find a snippet in there. The idea I had was that I had a moment [in Redemption] where Liara meets Aria on Omega, and Aria has a very negative reaction to a mention of the Collectors. And I thought that I didn't really mention why that is. It makes sense if you think about it, but maybe there's a story behind it. So that's the genesis of these 8 pages."
