Someone help me

Right so I've recently started playing centaura and I am quite frankly confused.

1. So antares are the bad guys?
2. Is there actually a video I can watch which propperly explains the lore
3. What is dead ahead
4. Badges and weapons, is there a specific best weapon, because idk I'm grinding for the 50 kills one right now, I hope it's decent. And anything else I need to know
