Using Q and E all the time by mistake. And it takes always much time to select a weapon. It's a bit annoying.

Is there an option to get the SoC, or CoP controls in HoC? This would be a real game changer.

Yes you can change key bindings. I couldn't find it at first because it's not obvious that it leads to a submenu.
I have to laugh because Q and E drove me nuts. I kept hitting them by mistake.
I changed them to leaning left and right.
See the attached images.

Thanks a lot.

I changed leaning to Q and E. Now leaning doesn't work anymore, but at least he doesn't consume all the medikits and energy drinks by mistake. That's a big progress and perhaps I'll find a solution for the leaning problem later... .

I forgot to mention that it did not work for me right away.
But it did work when I quit the game and restarted. So maybe it will work for you the next time you start the game.
