Pre alpha screenshots prove that you could wear 2nded weapons with heater on. At least there are a lot of ppl with hand axes and shields. Also, Im not sure if hand axe was even 2handed in this era.

On a side note, executioner axes (battle axes) are not shown on a player character, paperdoll only.

Edit: it seems a lot of things are not support by the original animations (metal shields, plate gloves etc.) Is there a way to fix it???

Edit2: nvm the side note, concentrate all your mental force for a subject issue

Equip the axe first then shield. (any axe)

I'll look into why battle axes don't appear on the character.
(There are 2 different battle axes, only one of them is currently not showing)

Where are you finding metal shields and plate gloves?

Ohh I see...

Yea I was talking about executioner axe-like battle axe.

From the knights.

PS. According to alpha screenshots the knights had heaters not metal shields because everybody weared blue, gree, red shields etc.
