Played more Hardline, yeah it is just a BF4 DLC that they decided to make into a full game. The two game modes available could have easily translated to a military theme, this is not groundbreaking stuff here. It's BF4 with cops/criminal skins and a few new game modes that aren't that interesting, and even if they were interesting could have had the same modes adapted to a military setting instead.
This is 100% cash grab, well scratch that, every BF is a cash grab at this point. The last unique BF was 2142. I'd honestly rather just play BF4.
