After the first hours of Fun some impressions:

Hidden Movement needed like Mordheim:
-I dont wanna watch every Step of every Ganger (especially in a 1v4 gangfight)
I liked it a lot in Mordheim to search the enemys... its tyring to wait for your turn

A lot less movement or more spots (aka traps) to lock your movement.

Story-Mode in your own Playergang (like Mordheim)

Movement in every Direction (so moving up and down consume BP). Defending a building is easy as you can blink up on every corner/Stage of your House for a clean shoot.
