Also, one can assume the circle with the + in it, on the card, is its HP, again, couldn’t find this in rulebook.
Yeah, I couldn't find it in the rules either. I figured that was the health by process of elimination and it's the same symbol as is on the health tracks of the mercs.
A lot of games have a nice graphic showing the cards with labels/pointers identifying all the info on the cards. This game could definitely use something like that.
