Necrons couldn't be fucked any harder than they are even if someone tried. I'm not going to attempt playing more of their campaign than what I've already endured.
They're so royally fucked I can't even find words for it.
They may be ancient horrors, but only to the nurses in their geriatric ward.
Once you've killed all four of Abaddon's lieutenants, you get a repeatable UE4 engine CTD.

Once the last lieutenant dies, the game will first run through the next mission brief, then debrief the mission you just completed, which struck me as strange - then again, I wouldn't bet on it not having been this way throughout the campaign.
Some ship hulls aren't lined up with the direction they're travelling in. This includes, but is in all probability not limited to, all Imperial Navy ship hulls.
I would've uploaded a screenshot, but every time I tried to take one with torpedo predictions for reference, the game took it with the menu screen up for some reason.
(So this is in all probability two bug reports in one.)
