Duplicate rewards for computer hacking
It is possible to duplicate the rewards (XP, credits, and stop/nuke items) for hacking a computer. Just save before hacking a computer and while you are on the "access granted" screen reload your save (do not press the "ok" button) and hack it again. This can be repeated as many times as you want per computer though failing or aborting a hack will reset the stacked up bonuses.
Easy experience
When hacking, save the game. Then hack the optional nodes but do not complete the hack. After you hack the nodes, load the previous saved game. Repeat the process. When you finally complete the hack, you will get all the nodes (from the previous times you loaded) on top of the nodes you get normally. Use this on the computer in Jensen's office for 500 experience points every time you load for easy Praxis points.
Hack everything possible if you have the required Hacking skill. This will result in easy experience points as well as possible access codes and credits.
Non-lethal takedowns and kills are worth more experience points than the lethal variety. Note: If you have the Reflex Booster Augmentation you can will earn 125 experience points from a non-lethal takedown.
In Hengsha, China every store has a back door. Open it, then walk inside for a Traveler bonus of 100 experience points.
Easy hacking
To keep attempting hacks without running out of hack attempts, when the system is alerted before you run out of time, press [Q] to cancel hacking, then press [H], and the failed attempt will not count against your limited number of chances.
Easy kills
Upgrade Hacking and Strength to be able to pick up turrets, which have unlimited ammo. Set them down or let them fire while you move to easily clear out a room. You will still get XP and headshots. You can also do this with robots.
Easy stealth kills
If you prefer to take your enemies down quietly but are be finding it difficult, find an indestructible object such as a barrel or container and take it with you. When you find a group of enemies, stand in a position where you want an enemy to approach. While holding the barrel, throw it next to yourself or close to where you wish your target to approach. The entire group will be alerted upon hearing the object slam to the ground or wall you threw it at, but only one should approach to investigate. The enemy will walk to the area alerted, stand where the sound came from, then begin to walk back after finding nothing. You can now knock them out or kill them undetected at your desired location. Note: If you throw the object a long distance, the investigating enemy may track the object's flight path directly back to your position. It is better to throw it nearby for repeated use.

Infinite XP
This glitch works anywhere, but the first and easiest place to do it is at Adam Jensen's computer, which is located in his office at Sarif HQ, after returning from the Sarif Manufacturing Plant hostage situation. Use the discovered Praxis Kit and an earned Praxis point to upgrade to Hacking Security Level 3. Try to collect as many Nuke Programs as possible to help speed up the process. The Nuke Programs can be collected in the Sarif Manufacturing Plant, or while searching and hacking into the computers around Sarif HQ. Before starting a hack, save the game. Hack all optional nodes, or the Network node to instantly complete the hack. Do not exit out of the hack or press a button to complete it; you will also want to make sure you are getting an +XP bonus. While using Adam Jensen's computer, hacking the special reward nodes will get you a +500 XP bonus. When you have acquired the optional nodes or captured the network node, pause the game, and load the saved game created before you hacked. Again, do not complete the hack. When the "Access Granted" window appears, do not select "OK". Load the saved game you created before starting the hack. Then, try the hack again. Repeat the previous steps, and capture every optional node or the network node. The game will keep your previous +500 XP bonus. For your second try, you will get +1000 XP. For your third try, you will get +1500 XP, etc. Do the trick five times to get +2500 XP. Make sure to keep loading and never select "OK" to complete the hack. Repeat this trick as many times as desired to get a lot of XP early in the game. You can always return to Adam Jensen's computer later in the game to repeat this trick, or try it on other hacking challenges throughout the game.

Picus Communications: Funicular
When you must wait for the Funicular to come up in Picus Communications, enemies will appear. Before pressing the elevator button, save the game. Use heavy objects to block both entrances into the room. Note: This requires the Move/Lift Heavy Objects Augment. You can use the two vending machines outside the room, two crates next to the security computer, and the turret in the centerto block the lower doorway and the side corridor. If done correctly, the guards will remain outside while you are waiting for the Funicular.
RoboCop reference
In Detroit, in the police station on the top-most floor, there is a Detective Alex Murphy. This is RoboCop's real name. If you sneak up on him and another police officer talking in his office (there is an air vent in the office) you will hear them talking about an old movie where a cop gets turned into a cyborg.
Saving Malik
You can save Malik from being killed in the Heng Sha ambush if you prepare yourself before the mission starts. While in Detroit, stock up on a sniper rifle or tranquilizer rifle, and ammunition for both of them (or weapons already in your inventory), EMP grenades (for the massive bot), and gas grenades. When you land in the Heng Sha ambush, take cover behind the wooden panel where you first start or behind the concrete pillars. Take aim at the heavy troops carrying the heavy machine gun first before you take out the snipers and ground troops. There should be some red barrels near the snipers if you want to conserve ammo. When the majority of the troops have been taken out, a combat bot should appear. Aim about mid-sky toward the bot for an accurate hit with the EMP grenade. Take out the remaining troops you have not dispatched yet and you should hear Malik tell you that the bird is fully operational and will thank you for saving her.
