There are at least two Dead Space references in Battlefield Hardline - check 'em out.
I guess the following could be deemed a spoiler, so if you're avoiding that sort of thing look away.
The best Dead Space reference is during a single player mission where you'll find a couple of criminals kicking back, playing Visceral's much-loved sci-fi franchise.
You'll see it in the video below at the around the 33 seconds mark.
You'll also find the Dead Space Black Marker monolith in one of the multiplayer maps, as captured by Reddit user ErMahGerdPerkemern's fiance.
Now, if the Line Gun was a playable weapon in Battlefield Hardline we'd be very happy bunnies.
