Just because something goes against your personal preferences, it doesn't mean it shouldn't be in the game.  There's nothing wrong with adding more content.   Besides, I think it's guaranteed that the majority of time and resources will be spent on the Space Marines and Tyranids.  Hey, I hate Space Marines (I'd rather have a challenge instead of pwning everything with my ceramic-digesting organs and whatever else they have), but I'm not going to crush other people's hopes.

That said, I read somewhere that it'll be unlikely that the Guardsmen are playable, although they might play parts as NPC's.

Getting back on topic, having the ammo counter on certain guns would be a very cool feature, if it is possible.

I voted for "Synapse", but I liked the idea of being able to play as Guardsmen in "Tree of Life".

Would it be possible to implement Guardsmen into "Synapse" as well?
