Took on Watch Dogs: Bad Blood DLC.
The DLC took about 7 hours and 24 minutes to finish its Campaign. This is not including any side stuff here, as I was focused on getting through the campaign; and didn't feel like getting caught-up in UbiSoft side-quests galore.
If you're all about Ubi side-stuff: there also might be a fair amount of that type of content also here for you - as the map here can get littered with side-stuff to do, in typical UbiSoft fashion - and gets littered with more and more of those, as you complete more main quests.
It's more Watch Dogs 1, if you liked what that game had on offer. If that sounds good to you, then you'll like this DLC. WD1 was basically a GTA-style game (3rd-person open-world shooter with some car-driving elements) with also some hacking & stealth elements. As many know, I really enjoyed WD1's gameplay; it's GTA-style combat mixed with especially those stealth & hacking elements that made the game a lot of fun to me. Though, I wasn't super-thrilled with its story & characters, as the game was literally loaded w/ cliches. Also, WD1 didn't really say much about the stuff it was tackling here w/ hacking, piracy, the Internet, Big Brother, human trafficking, etc etc.
Though, Bad Blood's DLC has a few tricks up its sleeve. The story b/t the two long-time friends, Raymond Kenney and Tobias - and this is even despite this DLC's brevity - still is way more interesting, personal, and whatnot...especially compared to Aiden's predictable and "meh" story from the base-game of WD. You can get a new RC item, which can be used to get through smaller areas you can't get through - and you can also use that for spying, hacking, cameras, and things of that sort. Also, there are some Bioshock-like pipe puzzles, though you can spin pipes around to try to hack these nodes too.
Regardless, I really enjoyed Watch Dogs: Bad Blood's campaign. It's more Watch Dogs; it has some interesting & cool new tricks up its sleeves for stuff (i.e. RC car and pipe puzzles); shorter main story length; and a much better & more focused story with much more interesting characters here (i.e. T-Bone and Tobias have much more personality than Aiden) make this DLC a winner.
