This seems somewhat expanded over what they were initially talking about.

GameZone said:Watch Dogs offers up six different modes that are instantly available from the in-game smartphone. Simply open up the map, scroll over to the multiplayer map and pick a mode. The game then auto matches you to others that are compatible with you. The six modes are Tailing, ctOS Mobile Challenge (which I cover here), Hacking, Race, Decryption and Free Roam. With the exception of Free Roam, I was able to get some decent hands on time with the rest of the online modes.
Free Roam:
[Nirolak's Note: This is the 8 player free roam thing, but it wasn't available at the event. The name probably makes what this is fairly inherent though.]
Tailing:
Tailing is the low risk and low reward option. In this mode, I had to essentially stalk another player without raising suspicion to myself. On my screen, I'm Aiden Pearce, on and the other player's screen, he's also Aiden Pearce, but to each other, we look like random Chicago civilians. My favorite part of Tailing is that the other player is never notified he's being 'invaded.' You can finish a Tailing mission without ever alerting the other player of your presence.
Hacking:
Once I got a taste of the low risk Tailing missions, it was time to put my Notoriety on the line through Hacking missions. Here I had to travel to a player's location and start a backdoor connection to their smartphone. Once this is initiated, the player is instantly notified and it becomes a game of cat and mouse, where the hacker tries to stay out of sight of the player that's now trying to hunt him down.
Decryption:
Decryption is the only one that's team oriented. A group of of players will go up against another group, trying to steal files and take it to a given location. I've played this mode (and Race mode actually) the least since I was so taken by Tailing and Hacking, but it was certainly enjoyable and does take some careful coordination to pull off correctly.
Race:
Race is as straightforward as it sounds. You pick from various predetermined races, get in a car and go.
ctOS Mobile Challenge:
Source 1: http://www.gamezone.com/previews/20...review-it-s-dark-souls-meets-assassin-s-creedLike I've mentioned in my Multiplayer impressions, one of the six online modes includes the ctOS Mobile Challenge. In this mode, players on the console can ping either random players or their friends with the app installed on their tablets. Likewise, tablet players can search for anyone with an open connection to their game. When matched, it becomes a sort of cat and mouse game, but instead of the tablet player being just the cat, he's more like a cat trying to build an elaborate mouse trap.
The goal of the console player is to drive through a certain number of checkpoints, while avoiding various traps and ambushes set down by the player, before time runs out. Sounds easy, right? Except the tablet player has some serious advantages. They essentially become a real life embodiment of Aiden Pearce, except being on the right side of the law. The app displays the entire city of Chicago, the player's location, and icons indicating traps that can be set off, such as blockers, burt pipes or causing a traffic jam. To keep things fair though, every trap is associated with a cost, and the only way the tablet player accrues more points is to drag his finger over the console player's location at all times.
