I think it would be interesting to develop stats for some additional weapons such as the katana, the chainsaw, and the RPG launcher.
The katana has a very high coolness factor due to the Walking Dead series and the new set of female survivors from Wargames Factory has a hilarious woman with an RPG launcher. That one would of course be very noisy.
I don't think the chainsaw would be an ideal weapon to use becuase of the noise, but it seems like every survivor set has them.
Just a thought. No big deal.
