Continuing with their pledge to give you a new Zombicide scenario every week, CMON has a new Invader scenario up on their website. The anti-matter generators are broken and making a lot of noise. Repairing them will not only help in the fight against the Xenos, maybe it'll stop attracting so many to that location.
From the post:
There antimatter generators sure are great... except when they aren't. They got out of alignment and now we need to fix them, but boy, do they make a lot of noise!
This is a scenario for Zombicide: Invader. Great for begginers, as it's not too hard and displays a lot of creativity. Enjoy!
