Ghost is a stealth-related XP bonus in Deus Ex: Human Revolution and its DLC. It is awarded along with Getting Things Done bonus for completing some of the main mission objectives, if the player met a certain set of criteria. This page is dedicated to revealing all these restrictions (including the ones that have no impact on this rating).
There are 3 general rules for qualifying for Ghost rating:
- Do not be seen by human enemies or bots. This does not include being seen briefly (without radar going red) when enemies simply become alarmed. Radar going Normal→Hostile or Alarmed→Hostile is usually a good indicator that Ghost bonus was ruined — but not always.
- Do not physically touch enemies (except when performing a takedown) and do not move objects in such a way that enemies may spot you (i.e. do not hold objects in your hands where enemies can see them, even when using the invisibility cloak).
- Do not let human enemies and bots see the bodies of their allies or other bots exploding.
Ghost is worth 500 XP. Receiving a Ghost bonus for a first time will earn the player the Ghost achievement. Smooth Operator is another stealth-related XP bonus in Deus Ex: Human Revolution (with its own set of rules).
This section is dedicated to revealing the enemies' reactions to different player's actions and their effect on Ghost rating.
- Enemy — a human enemy or a bot (security bot and boxguard). Bots have the same AI as humans, so most of the rules apply to them too. Take note that bots reprogrammed to friendly status with Robot Domination aug treat the bodies of their former allies the same way as if they were hostile to the player, meaning that if bot sees a body it will ruin Ghost rating regardless of bot's status. So if, for example, a reprogrammed bot kills someone it will cancel your Ghost rating, since it will see the body of the person it killed. Friendly bots and turrets can be destroyed by the player, even from within the bot's field of view, without affecting Ghost. Turrets have very simple AI and do not affect any stealth ratings in any way, so they are not included in this definition and examined separately.
- Enemy states (as they appear on a radar) and the states they transition into:
- Normal (gray)
- Suspicious (yellow) [→Normal]: applies only to cameras and turrets (when they see the player briefly).
- Alarmed (orange) [Lasts until enemy investigates the disturbance → Normal]: caused by small, innocuous disturbances. Even if several enemies witness the disturbance only one of them will stay alarmed and check it.
- High Alert (orange) [Lasts 80 seconds → Normal]: caused by more aggressive players' actions. The vision range of enemies in this state increases to 50 meters (from the normal 19 meters). Enemies become much more cautious: they usually run to check the disturbances when alarmed by player's actions, and try to cover each other if two or more enemies hear the noise made by the player. Enemies can also alert others while in this state.
- Permanent Alert (orange): appears only in a few scripted situations (Alice Garden Pods, TYM Penthouse, Picus, Rifleman Bank Station). It is, basically, a permanent High Alert state.
- Hostile (red) [Lasts 40 seconds → High Alert → Normal]: lasts until the time runs out or until an enemy gets disturbed again.
- FOV — field of view (vision cone).
- Investigate — a standard action type of action: enemy goes to a place of a disturbance, performs a 360 degrees look around, returns to a relaxed state and goes back to his original position.
- x in "Ghost" column — shows that corresponding action cancels the Ghost bonus.

There are some misconceptions regarding certain actions supposedly canceling Ghost, which turn out to be a completely distinct issue or not an issue at all.
- Enemy turning hostile: seeing hostile appear on radar is not 100% guarantee that you've lost Ghost. There are a lot of cases where this does not apply, like when an enemy is stunned by a grenade or Icarus stun, or gassed, or even hurt by the player. Likewise, in case of enemies seeing bodies no one turns hostile and yet that still cancels Ghost.
- Shooting an enemy without killing: what happens when you shoot an enemy is that
- he turns hostile (no effect on Ghost),
- he quickly turns in the direction the damage came from,
- he sees the player — it is the third action that cancels Ghost here.
- Quickly hiding after shooting will do the trick (but may lead to enemies triggering an alarm as a reaction to the gunfire, if there are alarm panels nearby). Also, being cloaked and shooting at enemy while standing in front of him is perfectly fine — you may even see the last known position indicator appear and enemies may open fire on your last known position — and all this still won't cancel the Ghost rating by itself.
- Reprogrammed turret killing enemies: it is a combination of enemies hearing turret's gunfire, coming to investigate it and seeing the bodies of killed allies that ruins Ghost in this case. As long as turret is used to kill the last standing enemy, or a lone boxguard, for example, Ghost will be fine.
List of objectives in Deus Ex: Human Revolution that award Ghost bonusEdit
As the case with Smooth Operator bonus there are some objectives in the game that have two mutually exclusive ways of resolving them, meaning sometimes it's possible to earn either Silver Tongue bonus or Ghost bonus, but not both. To see which way is more profitable XP-wise consult the Experience by area page.

- 4) Retrieve the dead terrorist's Neural Hub. Ghost and Silver Tongue bonuses for this objective are mutually exclusive.

There is a bug present in both console versions and the recent PC build (v1.4.651.0) of the original game, including The Missing Link (188.8.131.52), where (among other things) some Ghost and Smooth Operator bonuses may not be awarded to certain players when they complete an objective stealthily (see this video for an illustration). The details about causes and occurrences are not clear, but it seems that it has something to do with save game files of former playthroughs. If you're not getting a bonus you think you should get, you're most probably affected by the bug. It is strongly recommended to remove all save game information before starting a new playthrough. For PC users, the files are located at .../Steam/userdata/*UID*/28050/ for the original game, at .../Steam/userdata/*UID*/201280/ for The Missing Link and at .../Steam/userdata/*UID*/238010/ for Director's cut. Steam Cloud has to be disabled, otherwise it will restore all files from the cloud. For affected Console users, creating a new profile for each playthrough seems to be the way to go.
