- You can't burst with pistols, only with SMGs and assault rifles. I'll add that to the description.
Oh, silly me, I thought it was an SMG. Change the Burst tooltip where it says it needs 60 AP, that's what confused me.
- When you open the radial menu there and select the ability, it will assign that ability to the action bar. That is, if you have an item that can perform multiple stuff you pick which one you want bound to that button. I'll see if I can make that more intuitive.
Hmm, is the radial menu even needed for this item? You can't close closed shafts or open opened ones anyway, so the action should probably be chosen automatically.
- You can attack non-hostile creatures by using 'attack' ability. It's the very first ability in the 'quick invoker' and has the icon of your current weapon. In the future you will be able to open a radial menu and select that action from there.
I think it should be permanently on the bottom bar, since it's such a common action. Hotkeyed A for Attack. Or maybe left-clicking the weapon on the bar should work this way.
- You can unload your current weapon by holding shift and using the rightmost action button (Shift+Y).
I think right-clicking it should work too, since it does for unequipped weapons.
