Hmm watching the video of the G map now, and rubbing hands in glee, starting with 30 up means I'll be dropping my AW-Shuka first and taking advantage of the -3 up deployment cost passive. My AW-Elizabeth should also be a major asset especially versus those vamps.

Honestly compared to the 7th map the 8th seems easier, with 30 hp to soak you can afford to slip a lot of units through instead of crazy blocking so I would think 2* would be achievable for quite a few people. Because on the 7th map unless you can tank the litches and especially the boss their going to rip up your whole formation and cause all the enemies to pass though.
[Just noticing on re-watching the video 15 hp and total enemies of 51... so if you can hold solid and get 37 enemy kills you can pull out all of your units and soak the remainder for just one star loss. Not pretty I admit but better a clean 2 stars than just scraping 1 by trying to achieve 3 if your team is inadequate.]
