Just played 7 & 8.
Mission 7: It just felt like wave after wave of Shivans with little point but to just keep killing them... that may be what you were going for, but it felt really long. I don't have a solution or anything, just my thoughts.
Mission 8: I liked this rendition of the attack, Good work!
Though I was a *little bit* dissapointed that the Shivans weren't much more ferocious. I would have expected far more fighters, but I guess that could make this mission near unplayable. Again, just my thoughts..
Overall, enjoyable though.
Actually, I did learn 1 downside to this method of release.. I keep forgetting what happened in the mission prior. But that won't be a problem when they are packed into a campaign.
