Wow, cover now added to armour save, I did not see that one coming.
That's huge!
It seems like the basic rules once again got tailored to marines.
Standard marines in hard cover will be untouchable with basic weapons, same thing for terminators in soft cover.
If 2++ with re-roll was bad, it just got worse.
I will also from now on refer to close combat to "the pistol phase".
Heavy weapons will be even more available, the phrase
"tread lightly and carry a big gun" echoed in rules format.
