I've been reading the rules, getting ready to demo the game for our store, but I have a question regarding how each player gets new units during the game. I know there are Order cards that allow players to get things like Imperial Army, Imperial Tanks, Titans, Cultists and Daemons, but how about Space Marines on either side? There doesn't seem to be any indication about getting more of them. And is there any way to get any units outside of Order cards?
And in the first scenario, it shows the Imperial player having all five Heroes, but the Traitor player only having Horus, Angron and Mortarion. Where are Fulgrim and Magnus? Do they have the ability to show up later or what?
