I engaged Hypnos Tyrannos today in Rens at a SoCT facility with my flagship, the Jormungand. It proved a challenging fight at first, due to it being a turret platform and the Hypnos cruiser going well over 1,1km/s. However, it seemed to orbit my ship precisely at 34 kilometers away, and engaging my own microwarpdrive I could about match it in speed, forcing it to turn away and flee from my ship, reducing transversal signifigantly, letting my ships autocannons shred it with impunity. Phased Plasma rounds seemed nominally effective, taking considerable chunks of shield and armor off it with each volley. I will have to test if other ammunition would be more effective.
I also tried to engage it with drones, but for some reason my drones kept disengaging constantly. Somekind of interference seemed to be at play, I haven’t yet reviewed the drone operation logs.
And lastly, all of the Sleeper-derived drones accompanying the Drifter Strike Cruiser warped off once their apparent leader was dispatched. Among the wreckage I recovered a Sleeper Data Library and somekind of neural booster.
Having not participated in anti-Drifter operations previously, I do not know how hard these are usually to defeat, but I concur with the OP, that it seemed “relatively easy” to disperse.
Edit: Additionally, damage levels were tolerable with a so-called omni-tank, I had to engage a shield boost once or twice, but from my very limited experience, these Sleeper derived drones do not seem to possess the same level of destructive power as their usual Anoikis counterparts, similarly, I was expecting the damage from the Drifter cruiser to be signifigantly higher judging from reports I’ve read - but as said, I have no prior experience in engaging Drifter vessels.
