Let's not forget some of the changes to combat too.
Attack animations have changed, so expect some frustration if you're used to playing the original M&B.
Throwing weapons can be switched between melee and ranged by pressing "x".
Athletics and running speed in general has been nerfed.
A slight change, but during arena and tournament battles, archers have knives as a side weapon.
You can press "g" to drop weapons/shields. (I think that's been there since the old M&B though.)
You can pick up the arrows/bolts/throwing spears/axes that have been fired by yourself and other troops. I think if you've got godlike reflexes, you can even snatch projectiles out of the air too.
Fallen troops ALWAYS drop their equipped weapons/shields/ammo, but only if they were using them when they were beaten.
That's what I've noticed so far.
Is there any way of stopping your companions from joining fights? My tracker and my doctor keep joining me in battle and they ALWAYS get wounded. As far as I know their skills don't come into effect until they're out of the "wounded" state, so the doctor especially isn't really helping. Now I hope I'm wrong in thinking that, but if not, I'd like to be able to keep them healthy.
If they do show up in battle despite using Janet's method, set them to a different group type and tell them to stay back.
