-New single-player campaign - Puts you in the role of T-Bone, eccentric hacker and ally to Aiden Pearce
-Conspiracy! - a new Digital Trip which sets you on the hunt for cyborgs
-The Untouchables Pack - Go oldschool with some classic Chicago mobster film gear including a 1920s mobster outfit and a M1 SMG (in North America, the Untouchables Pack will only be available with the Season Pass)
-Additional single-player missions, outfits and weapons
-One week early access to all Watch Dogs DLC
All that, for 25% less than what it would cost to buy each individual piece of content
This DLC pack is worthwhile i just gave 4/5 stars as i think it should be already included in the game, normally DLC appear even months after game release, but when you get a DLC on the same day as the game release day that makes you think: "money grab?"
The new weapons and outfits need to be either unlocked by completing an extra DLC added mission or purchased in any store on the map.
Most outfits are just different color and/or just a bit different design than original game ones so here it goes down to 3/5 stars as this isn't what people expect when they read "new outfits" it should rather say "new colors of old outfits"
But now you get a Tommy smg and a classical gangsta outfit from 20s and thats a nice touch, welcome to Chicago!
If you like the game you will may find it worth the money, i think it could be cheaper or as i wrote before, should be included in the base game
