1: do blueprints appear at specific points during the campaign? I'm paying a mission that seems designed for flamers or plasma cannons but I have neither yet

2: are certain units ARBITRARILY locked? I have been unable to use heavies for quite a bit now (at least 4 missions) ... it's more than annoying really.

3: why is the progression of the Tyranids so much faster than the Space Marines? I'm playing a mission each and I have all the units and almost all upgrades for the Xenos but nearly nothing for the terminators (like almost no weapons...no modules...not even half the upgrades....wtf...).

Thank you!
