After roughly 20-30 hours of blindly playing XCOM 2 and seemingly doing pretty well, I ran into a situation where I could not prevent the Avatar Project from being completed (I had no radio comms, because I didn't realize I needed them and I was on the 2 week timer before Game Over and the nearest facilities were 3 uncontacted regions away...).
Long story short, I had to start over. I did manage to complete Shen's Last Gift on the previous playthrough and the SPARK unit I received was immensely helpful, but I really do not want to complete that monstrous mission all over again. I noticed there is an option to not include the DLC missions when starting a new game, and that you are able to access all DLC content without doing them, but it didn't say how. How do I unlock the SPARK units without doing Shen's Last Gift?
