Take a very long time to finish.
Gina and I did our first ever task force missions earlier today, running errands for Positron with a friend of ours. We started around noon, and I don’t think we finished until around 4 or 5pm. It really started getting old after the 6th mission, and we were all glad when we completed it. None of us really gained any experience out of it, as I was 25, Gina was 16, and our partner in mayhem hit 16 shortly after starting. The biggest benefit was probably the 100k prestige we racked up, which I immediately put to good use in the base.
On a better note, I’m enjoying running around and exploring all of the newer content that’s available. It’s a far cry different from the standard, run-of-the-mill “defeat these villians in this cave/office building/sewer” missions that make the game only playable for a few hours at a time. I just hope there’s more of it ahead.
