Ok, I just did the mission for Shen's Last Gift. I cried
The mission itself was a BLAST. Wow. Thankfully I figured I'd be fighting a lot of robots, so I brought a lot of Grenadiers, grenades, and was able to just shred the fuckers to death. SPARK is nothing to laugh at, either.
While what you get from the DLC isn't all that amazing, the mission itself is simply perfect. I loved it.
Edit: Hmm, actually I just ran into a bug. I'm on the roof, and I keep glitching out. My guys won't properly end their turns, and if I move too far onto the roof, I get stuck on one unit. If I try to immediately end the turn right from the start, it just sticks and does nothing.
And if I try to load the save at the end of the turn on the previous level, it locks the game up...this is fun.
