Well I just had my first death...
Decided to try out attacking a Space Station.
Upgraded my Cannon with damage/cooldown (not fire rate as that seems to be bugged backwards right now) and outfitted the best shield upgrades (not convinced they're working, I seem to take the same damage with or without them) and attacked it.
Within a minute or so, my radar looked like this:

Every dot you see is a hostile.
Holy. Shit.
This is the first time while playing that I feel like Sean UNDERPLAYED the severity of how difficult taking one of these things down is going to be, good lord...
