In the screenshots released of Aiden's smartphone functions, you can see an icon that resembles the symbol of the Assassin Order, except flipped, connected to Pieces of Eden. Both are from the Assassin's Creed series.
If you're low on money, you can play poker in the Loop and hack into the security camera to see your opponents' cards. You can also hack into the bank accounts of rich NPCs to get more money. Getting more money should never be a big problem, so don't save it when there are things you need to buy.
If you have lost your vehicle or need to get somewhere fast (or if you are being chased), you can hack trains at any point on the tracks to start/stop them. If you're up high, you can hop on the roof of the train instead.
Keep a grenade launcher with you in case you find yourself up against tough enemies or enemies in vehicles. You should always have a silenced pistol and an assault rifle with you, as well. Having good weapons should be your priority.
Focus is a very useful skill. It's a good idea to unlock it as soon as you can, so you can use it to slow down time and plan out your strategies.
Be sure to devote some of your skill points toward driving, as you can't use a weapon while in a vehicle. You'll want to increase your vehicle's defense, and pick out a few other upgrades to secure yourself on the road.
Once you've use some skill points on Focus and driving, you should concentrate on your hacking skills. Crafting is another useful skill to improve, and you might want to prepare for tougher battles later on by unlocking the skill that will allow your melee attacks to kill enforcers.
Hack lifts and forklifts to carry yourself up to rooftops. Once you reach the roof, lower the lift/forklift so your opponents (whether they are NPCs or other players in multiplayer) won't be sure you've gone up. Use your high vantage point to keep an eye on them and take them by surprise.
Hack into cameras to see where your enemies are and kill them from a distance. Use stealth whenever possible. You can lure enemies into traps, trigger their own grenades, and more. Silenced weapons are also an option.
In addition to being useful in combat, hacking cameras can also help you find new paths for you to take and unlock doors. You can move from camera to camera, and even move to a camera in a different building.
For the cup and balls scene (where you have to guess which cup the ball is under) after the guy is done mixing the cups and it's time to choose, hit the options button and the graphics renderer will show where the ball is!
Eight Burner Phones can be hacked in the city to hear the conversations between Maurice and the caller. Search the locations described below to find them all and earn the Vespid LE vehicle and the "Sanity Check" achievement.
Phone #1 - This is in Parker Square, but you will find it as a required part of the campaign.
Phone #2 - Go to Pawnee and circle around to the back of the Fish Restaurant. Go inside the blue shack to find the phone on a cabinet.....
Then start killing nearby pedestrians, if they try to call the police, shoot them.
Do this until you have five stars.
Then find a boat and escape before getting detected by police.
If police start chasing you, then you can't get the Trophy/Achievement, so escape using jam comms.
Weapon Crates Locations Guide
Nine Weapon Crates are hidden in garages throughout the city. Search the locations described below to find them all, which will earn you the weapons and items from within the crates, the Spec-Ops Goblin weapon, a side quest, and the "Saturday Night Special" achievement.
Crate #1 - Go to Parker Square and head southeast until you reach a garage. You'll need to use CCTV cameras to find the terminal on the roof of a nearby building. Unlock the garage and go inside.....
You aren't powerful enough to fight the police very often. Try to avoid them. Once you've committed a crime, your map will mark witnesses as red triangles. The triangle's border will fill up with red as the witness puts a call through to the police. Try to stop these witnesses before they can complete the call, preferably through non-lethal means to avoid creating new witnesses.
If you know there are too many witnesses for you to stop, leave the area. The ctOS scan will begin....
