I might've mistyped, I was able to figure out how to utilize the handgun and the baton though I only achieved this be having just the one equipped. If I wanted to use the hand gun I'd
only have the handgun assigned to a slot and same for if I wanted to use the baton I'd
only have the baton assigned to a slot.
I ultimately wasn't able to figure out how to seamlessly switch between the two, I did look via the game options for control bindings but I was only to find things like mouse sensitivity and stuff like that............ though I must ask (because I am 'le stupid' whereabouts the "how to control" file is located?
Alsooooooooooo... what's this about an art pack? Me wanna look! 
That thar be some awesome art, I assume the "failed rescue" art pack is the one depicted on twitter? But yeah, that thar be spectacular line art and colouring.

EDIT: I'm seeing reference to a "big POC build", I'm inferring that POC is "Proof of Concept" ? Also, what bangs and whistles are envisioned to be included in this build or is it too early to disclose that?
