The AI in a game can't use a game mechanic the player is capable of with the same item or character.Tropeworthy? Better Name
Derived from a Lost and Found query. Formerly titled Secret Player Moves, Forbidden To The AI. Nintendo Hard, while others are blatantly stupid. But in general, you expect computer-controlled characters in multiplayer games to be capable of doing everything the player can. This trope is for when they can't. This is not about the player exploiting Good Bad Bugs, but rather when the item or ability in question is explicitly designed to be capable of something that both the AI and the player can do (sometimes depending on context), but the AI for some reason does not. This can be particularly infuriating (or alternatively, worthy of relief) if the action is an interface command. In some cases this may be an Anti-Frustration Feature, or a case of Dynamic Difficulty where the computer only starts using them when you get good. Sometimes general difficulty setting choice (the "Easy", "Hard", etc. settings) may also regulate what they can and cannot do. Common forms include:
- Many non-Fighting Games featuring a block/counter mechanic only have the Player Character able to do it.
- Computer characters frequently can't crouch or jump.

- In Master of Orion the computer can't direct more than one attack per turn. That means when you and the AI are busily blowing up the helpless civilians on each other's planets you can get several times as much damage in with a smaller fleet.
- The AI in Civilization has a mixed history for nukes. Some versions never let the AI use them. Others have the AI spawn them out of thin air. Later versions tend to play fair.
- The original Assassin's Creed I had the player character instantly drown if they attempted to swim, while the AI didn't even attempt to enter the water. In all other installments, the player character can swim, but enemies still drown instantly, allowing for easy getaways if the player is ever able to swim away. No justification is given for why even characters armored as lightly as the player have Super Drowning Skills.
Beat Em Up
- In Dynasty Warriors 7, players with a characters EX Weapon equipped, gains access to the Ex Attack. When a player performs a certain charge attack. Which the computer doesn't use.
- Also the player can change weaponsnote for better range, attack power or just because. The AI on the other hand are stuck with the same weapon.
- At lower difficulty levels, the AI in the Magic: The Gathering: Duels of the Planeswalkers games will never activate the "pumping" (paying mana to temporarily increase power and toughness) abilities of certain creatures.
- In the arcade version of Street Fighter II: Champion Edition, the AI-controlled Sagat would never use the Tiger Knee special. Meanwhile, the player character had no problem doing this. Apparently it was an unfinished special move that lacked new sprites, sounds and needed a unique button combination. It was later fixed for Street Fighter II: Turbo and every incarnation since.
- In the original Half-Life, Gordon Freeman can climb ladders and duck to fit through crawl spaces; the other NP Cs cannot (other than animals small enough to fit in the crawlspaces). This limits, for example, how far Barneys can accompany you as backup.
- AI players in Left 4 Dead and Left 4 Dead 2 can do nearly everything the player can, except for inflicting Friendly Fire damage and wield thrown weapons like pipe bombs or Molotov cocktails.
- Halo 2: A human player flying a Banshee can use a fuel-rod cannon as a secondary attack. The AI can't. This was not available in online multiplayer.
- In the Borderlands series the AI will never intentionally target Exploding Barrels (though they may still hit them when they were aiming at the player).
- Bots in Team Fortress 2 cannot use unlockable weapons. Even with just stock, engineer bots cannot haul buildings (instead detonating their old ones when the time comes to move the rear lines forward) and Soldiers/demomen cannot Rocket Jump.
- Some secret characters in the Castlevania series are bosses that you eventually fight in their respective games; some of them have moves that they don't use by the boss versions (meanwhile the majority of them have Secret A.I. Moves).
- In Mega Man ZX Advent, where you can copy the forms of the bosses themselves instead of merely Power Copying like in previous games; Atlas (in Ashe's story) as a boss couldn't fire her fire bombs forwards like Ashe could with her form.
- In Mega Man X, whenever Zero becomes a boss, he never uses any move he can acquire from the bosses (not even his standard 3 slash combo); he uses moves the player can never use instead.
- In Kirby's Dream Land 3, a computer-controlled Gooey cannot use Power Copying like he can when the second player controls him.
- Crash Team Racing:
- The computer-generated racers will never use shortcuts (when there is any), not using certain weapons normally available for players (turbo boosts, warp balls, bubble barriers, etc) nor will they leave trap weapons when they're offscreen.
- The beakers (normally a trap weapon) is able to be thrown forward, and the roller bombs (normally a forward-fire weapon) can be rolled backward. None of the computer characters do this.
- The boss racers in the Adventure Mode works differently; they still leave trap weapons (constantly) even when they're far behind or in front of you (and in Pinstripe's case, he also rolls the bombs backwards) but the other limitations above apply.
- It truly becomes a challenge in the Time Trial mode against Oxide's ghost when he's able to use shortcuts in the track.
- In LEGO Racers the AI opponents never achieve the level two turbo start, never power-slide when turning, and with one exception never use track shortcuts. The exception is Veronica Voltage, opponent in the Time Trial mode, who is also immune to track edge friction (rendering beating her Nintendo Hard).
- Quite possibly the most infamous example is Big Rigs: Over the Road Racing. This is the racing "game" in which the AI is not given the option to win, stopping just short of the finish line, and that's after a patch.
- In Super Mario Kart, opponents in a race are unable to use items generated from item boxes. The AI compensates in several ways.
- Warcraft III: While the standard AI will hire zeppelins (and occasionally use them, but only if there is no other way to reach an enemy base), they will never buy ships, mercenaries, or neutral shop items, or use instant-reviving taverns.
- The Level Editor for StarCraft I has several grades of AI available for map builders. The ones labeled "Campaign Easy" and "Campaign Medium" are restricted on what units and buildings they are allowed to construct (for instance, "Zerg Campaign Easy" will only build basic zerg units such as zerglings and mutalisks).
- Dawn of War: Several moves/upgrades are never used by the AI, such as ork Burna Bombs, various morale-reducing abilities, or Tau commander weapons. That last one is particularly stupid, as it deprives them of both a short-range anti-infantry and long-range anti-armor.
- In Command & Conquer: Tiberian Sun and Command & Conquer: Red Alert 2, the rules.ini files had a special flag called "AIBuildThis = no" on some of the units/structures that the player could build.
- Solatorobo: During the racing portions of the game, enemies never drift into turns, collect but don't use the speed-boosting crystals, and use items infrequently.
- Zigzagged in the Dragon Quest series, where the non-main character PCs can be controlled by AI. The allied AI is (thankfully) far more effective than the enemy's, as it knows which enemy is the weakest and will attack it first until it dies, then move to the next, or if it's buffed (if a Squishy Wizard starts attacking instead of throwing fireballs, the enemy likely starts with spell reflection, which the player can't see). By contrast, two enemies will for example first buff their group, and the other will then nullify all magic effects on all fighters, wasting their turns.
- Almost all items in Persona 3. This is exceedingly frustrating, due to the game's Manual Leader, AI Party. Despite a spared item pool, your party cannot use anything but the two weakest healing items. As such, if your character is incapacitated through a status effect and you don't have a member that knows the counterspell, you're left as a passive observer until it wears off.
- In the main series Pokémon games, besides having access to a much more extensive inventory the player seems to be the only trainer to be able to foresee the Pokemon his/her opponent will use next and switch the active Pokemon without taking a turn if necessary. This is called the "Shift" battle style and it's enabled by default on the options screen. However it only works in single-player mode against the AI. In multiplayer battles you don't get the opportunity for a free switch-out when your opponent sends in their next Pokemon.
- In Pokémon Colosseum and Pokémon XD, the player can use the "Call" command on Shadow Pokemon that have entered Hyper/Reverse mode (which occurs during the purification process). In XD, the player can also use the Call command on their own Pokemon to wake it from sleeping or raise its accuracy (without having to use an item for this).
- Final Fantasy
- Final Fantasy XII is this throughout most of the game thanks to the gambit system. Since you don't start out with quite a few gambits, the AI-controlled characters will be severely limited to what they can do. It is subverted later since you can buy all the gambits though.
- Final Fantasy XIII has this problem when it comes to using Full ATB Skills. AI controlled characters will never use full ATB skills and since you can't change characters in-battle, you're stuck with only using 1 character's full ATB skill each fight.
- X-Universe series:
- Non-player-piloted ships never use their WASD strafing thrusters.
- X3: Terran Conflict introduced M7M missile frigates and M8 bombers to the X series, both of which are designed to fight by pouring enormous salvos of missiles into the target from well beyond gun range. The player can remotely command their M7Ms and M8s to do so using the Barrage command, but AI ones use the same AI as every other ship class, meaning they will fire missiles rarely and singly. This goes for both NPCs and Player Mooks, and is fixed in the Expansion Pack Albion Prelude.
- The Yellow Squadron in Ace Combat 04: Shattered Skies cannot fire QAAM missiles, even though they fly one of the few plane models in the game that can carry these missiles. That's because QAAMs are ridiculously overpowered in AC04 (one shot kill plus nearly impossible to shake off), and if the Yellows were allowed to use them, in addition to their other advantages, the game would become literally unwinnable.
- Operation Flashpoint: With good aim and a lot of luck, you can shoot down enemy helicopters with pretty much any weapon by shooting the crew through the windshield when they line up for a pass, or simply filling the vehicle with holes until its engine quits. Of course, you'll never last long enough to do so if you stand out in the open, but if some good cover is at hand and you have the nerve to try, it's possible. The AI never try to shoot at helicopters with anything but guided anti-aircraft missiles.
- In FTL: Faster Than Light, the AI is unable to manually open its doors to vent the atmosphere and attempt to suffocate the player's boarding party (although note that many AI-flown ships lack exterior doors altogether), or funnel them into the Medbay where its own crew is at an advantage.
- In Ten Minute Space Strategy, building space stations is something only players' colonizers can do. AI colonizers are limited to founding colonies on planets.
