The ''VideoGame/CallOfDuty'' series does this frequently:
* In ''VideoGame/ModernWarfare'':
** In "F.N.G.", if the player triggers the target at station one and then runs back to the platform where Gaz is standing before shooting at it, Gaz will ask you what you're doing and tell you to get back to the first station. You can also get a [[NonStandardGameOver wide array]] of failure messages for many circumstances, including shooting the [=TVs=] at the training course ("You endangered your squad!") or shooting too close to Price ("You almost shot Captain Price!").
*** About half of the level's objectives were DummiedOut; Price has a possible line that references it if you start doing worse at the CQB test, saying "perhaps it was a mistake to let you skip the obstacle course".
** During "Crew Expendable," if you move too far from Price after he tells the SAS team to stick together, you'll be ambushed by a single unique enemy soldier with an equally-unique Desert Eagle that will two-shot you.
** In "Charlie Don't Surf", it's possible to see an enemy technical truck driving far in the distance as you enter the town. If you shoot slightly ahead of it and view it as long as possible, there's a special animation where the driver's door opens and a corpse rolls out. This cannot be done anywhere else in the game.
*** In addition, if you take out that technical, the one that attacks you on the road won't appear, with the implication being that it was the same vehicle.
** In "All Ghillied Up", a scripted encounter involves an enemy helicopter passing over you. Normally, you're supposed to hit the deck and let it pass. There are some Stinger missiles located in the building just before that happens. Should one use a Stinger to shoot down the chopper, Cpt. [=McMillan=] will actually comment about it, sardonically telling the player to stop showing off.
** Using cheats on "Game Over" will produce a wide variety of unique effects that can't be triggered in any other way. If the player activates the "godmode" cheat and scores a hit on the Hind chasing the truck with an RPG (which is next to impossible) or kills the maximum number of enemies on the bridge before the tanker explodes (which is very difficult), the ending changes - instead of Zakhaev executing Gaz, a random SAS soldier (usually named Pvt. Cook) inexplicably gets up from the dead and melees all three Ultranationalist soldiers (including Zakhaev), with the rest of the ending proceeding normally and the player not having anyone to shoot.
*** Zakhaev has a scripted animation for when he turns around to shoot you while you're laying on the ground at the very end, where he will take three shots then start walking away. If you use cheats to survive that, once the animation ends he has regular combat AI, and will continue shooting you, even following you around if you use the "noclip" command to move. They even accounted for how a man with only one arm is supposed to reload a gun - he'll [[ThrowAwayGuns let his Deagle drop after seven shots]] and pull out a new gun. It's hit-and-miss, though, as he's animated to hold the Deagle like a rifle, including letting it fall on a sling so it hovers over his belly, and once he pulls out the second gun he'll simply play the normal reloading animations, apparently shoving in new magazines with a phantom limb. Also, if you use "noclip" as Kamarov and the Loyalists arrive to rescue you, you can watch as the medic continues trying to resuscitate Price after the stretcher is lifted up into the air, and the medic pounding on his chest at the end (which can't be seen in normal play).
** In "Blackout", if you follow Gaz to the fusebox instead of waiting by the door with Price, he'll tell you to go back and wait.
** During the mission before handling the nuclear bomb launch crisis, it is possible to be killed by a hangar door opening by jumping on it before it fully opens, complete with the message "You were killed by the hangar door".
** The UpdatedRerelease adds Makarov and Yuri to "One Shot, One Kill" as a ContinuityNod to [[spoiler:Yuri's flashback in ''Modern Warfare 3'']]. If you shoot Makarov after shooting Zakhaev, you get an achievement called "TimeParadox" for pre-empting the next two games. Shooting Yuri, on the other hand, results in a [[NonStandardGameOver game over]] for "friendly fire."
** The last field in "Hunted" seems to be impossible to cross without being spotted by the sentries and triggering a running shootout as you flee to the other side to escape the helicopter. However, you ''can'' cross without being spotted by the patrolling guards if you manage to quickly get close to the one on the right, crouch and sneak up and then knife him, and then crouch and move back before the other sentries turn. You'll still get into a firefight once you get to the end of the field and enter the greenhouses beyond, though, since that cannot be skipped.

** In "All Ghillied Up" there is specific dialogue from [=MacMillan=] if you kill the guard patrolling outside of the church in different locations, and the lookout in the tower may or may not spot the corpse depending on where you kill the patrol.
* In ''VideoGame/CallOfDutyModernWarfare2'':
** If you wait long enough at the basketball court during "S.S.D.D", a Ranger will ask you to get off the court. If you wait even longer, he asks you to wait your turn, then expresses indignation at what you're doing.
** If the player decides to run across the completed bridge after it's been repaired in "Team Player", you get shot by a sniper and the game chides you with a special message that "Maybe it's safer to stay with the convoy."
** The UpdatedRerelease adds [[spoiler:Yuri crawling slowly after you]] to "No Russian" as a ContinuityNod to [[spoiler:his flashback sequences in ''Modern Warfare 3'']].

** Also in ''Black Ops'', the introduction of the "oversampling" mechanic for semi-auto and burst fired guns, where attempting to pull the trigger faster than the weapon can actually fire will caused trigger inputs to get intermittently skipped[[note]]A major improvement from ''World at War'''s anti-modded-controller measure, where exceeding a weapon's firecap by even just a bit will cause a permanent rate of fire penalty for the offending weapon for the rest of the match. The problem? For some semi-auto weapons, it is easy to exceed the firecap on accident.[[/note]] The M14 and FAL, in particular, will "jam" in this fashion if fired too fast. This is meant to be a deterrent against hackers, so that the M14 and FAL don't turn into death lasers.

** The KSG fires regular buckshot in singleplayer, but slug rounds in multiplayer. The models for the shells loaded into the multiplayer version are properly green, like real-world slugs.

** In "F.N.G.", if the player triggers the target at station one and then runs back to the platform where Gaz is standing before shooting at it, Gaz will ask you what you're doing and tell you to get back to the first station. You can also get a [[NonStandardGameOver wide array]] of failure messages for many circumstances, including shooting the TV's at the training course ("You endangered your squad!") or shooting too close to Price ("You almost shot Captain Price!").
*** Price actually has a possible line referencing the fact that about half of the level's objectives were DummiedOut ("You're getting slower. Perhaps it was a mistake to let you skip the obstacle course.")

* In ''Modern Warfare 2'':

* In the ''Modern Warfare 3'' mission "Turbulence", if the player attempts to reload the AK-74u or Five-Seven as the plane stalls and floats in zero-gravity for a few moments, the magazine will float away and spin in the air instead of being thrown away normally. This cannot be done with any other weapon.

*** If the player uses the "noclip" command to move around while they're laying on the ground, Zakhaev will follow your movements and unload his gun into you. They even accounted for how a man with one arm is supposed to reload a gun - after seven shots he [[ThrowAwayGuns tosses it and pulls a new one]] (though he only does it twice before pulling out a gun with BottomlessMagazines). Also, if you use "noclip" as Kamarov and the Loyalists arrive to rescue you, you can watch as the medic continues trying to resuscitate Price after the stretcher is lifted up into the air, and the medic pounding on his chest at the end (which can't be seen in normal play).

** The UpdatedRerelease adds Makarov and Yuri to "One Shot, One Kill" as a ContinuityNod to [[spoiler:Yuri's flashback in ''Modern Warfare 3'']]. If you shoot Makarov after shooting Zakhaev, you get an achievement called "TimeParadox". Shooting Yuri, on the other hand, results in a [[NonStandardGameOver game over]] for "friendly fire."

The problem? For some semi-auto weapons, it is VERY easy and physically possible to accidentally exceed the firecap.[[/note]] The M14 and FAL, in particular, will "jam" in this fashion if fired too fast. This is meant to be a deterrent against hackers, so that M14 and FAL don't turn into death lasers. This mechanic is carried over

* In ''[[VideoGame/CallOfDutyBlackOps2 Black Ops II]]'', the Tactical Insertion equipment displays coordinates on its LCD display. The coordinates are, in fact, almost always accurate to the map that they are set in. For example, the multiplayer map "Drone" is set in Burma. If you read the coordinates and type them into Google Earth you will end up smack dab in the middle of Burma. This must have been quite a lot of work, as every single map in the game has this feature, including DLC.

* In ''Black Ops'', some firearms are held in such a way that you can see your character's watch. When playing as Agent Hudson, his watch actually tells the correct time given by your system clock. When playing as [[spoiler:Mason]], his watch gives a completely random time that changes periodically. This is very subtle foreshadowing of [[spoiler: the fact that Mason's grip on reality is at least partially unhinged.]]

** In the remastered version of ''Modern Warfare'', during the "One Shot, One Kill" mission while assassinating Zakhaev, if you shoot the driver in the jeep behind the meeting spot, you will get a secret achievement titled "Time Paradox," because you ''just shot Makarov'' and averted the second and third games from ever happening. But if you shoot the passenger, you get a NonStandardGameOver saying "Friendly fire will not be tolerated" for killing Yuri.

** The metal detectors in "No Russian" are not just a one-time scripted event. Mess around with the ones in the multiplayer version of the map, "Terminal", and you will notice that, not only do they go off if you run through them, but throwing any lethal equipment or launching a rifle grenade through them also sets them off.

** In the remastered version of ''Modern Warfare'', during the "One Shot, One Kill" mission while assassinating Zakhaev, if you shoot the passenger or driver in the jeep behind the meeting spot, you will get a secret achievement titled "Time Paradox," because you ''just shot Makarov'' and averted the second and third games from ever happening.

** In "All Ghillied Up", a scripted encounter involves an enemy helicopter passing over you. Normally, you're supposed to hit the deck and let it pass. There are some Stinger missiles located in the building just before that happens. Should one use a Stinger to shoot down the chopper, Cpt. McMillan will actually comment about it.

** Also in ''Black Ops'', some of the semiautomatic rifles will jam if fired too fast. This is meant to be a deterrent against hackers, so that the M14/FAL doesn't become a death laser.

** If the player decides to run across the completed bridge after it's been repaired in "Team Player", you get shot by a sniper and the game chides you with a special message that "Maybe it's safer to stay with the convoy." Later on at the end of the mission, if you shoot General Shepard in the arm or the leg before he begins speaking to you (which happens almost instantly), he adopts a battle stance and looks at you in disgust, which makes the mission impossible to beat.
*** If you decide to glitch out of the level and visit the road north of the school (which is impossible to access normally), you can see a Spetznaz flag flying on top of the school - the only time in the game any flag is seen in such a fashion.
** At the end of "Contingency", if you decide to follow Price towards the sub instead of taking position on the rooftops to protect him, he will tell you to get back to your assigned place. That's not the "dev" part, though. By using the "noclip" command, you can follow him inside the sub and watch as he goes through the whole procedure of arming the nuclear warhead and firing it! This is due to a section of the level being cut from the final game.
