We've had enough of the Slugs, and we head out of their territory, in the hope of finding safer passage to Federation-controlled areas. There's a Rebel ship there, waiting; possibly for us, possibly just waiting in general. It seems to have adaptability to a wide range of possible situations: its weapons feature a weak laser, a weak missile, and a weak beam drone, and it has a wide array of defences: anti-missile drones, anti-drone drones, and shields to block lasers and beams.Causeway (n). A featureless stretch of space punctuated by beacons, used to allow quick passage past large areas of space in which there are no interesting objects.
However, there's something to be said for specialisation. Even without our bodged-together shields upgrade and the reassuring blue barrier it placed around our ship, it couldn't get through our shields without help from its missiles, and we have a drone circling round us defending us from those. We shoot every one of its missiles out of the nebula, and out of ammo, it's a sitting duck.
At this point, we discover a new and unexpected defence: the thing can fly really quickly. It, perhaps stupidly, isn't trying to run, rather it's weaving around to try to prevent our EMP shots connecting. We're going to win this battle eventually, but it might take a while.
