There is actually a two player mode in which the second player controls the duck that player one is trying to shoot. This option is only available in game A. This was stated in the game manual, on page 3.
Early on in Level 5 "Barons Hed: The Fallen City", if you scare the villagers in Barons Hed, they will run away, and you can follow one fleeing woman who will open the locked door of a house near a bridge. If you can get inside the house fast enough, Max from Sam & Max, a franchise whose first game Sam & Max Hit the Road was developed and published by LucasArts, can be found inside sitting in a chair wielding a modified Bryar pistol (which is ironic since the Bryar pistol is already a modified Bryar rifle) that shoots highly-damaging green bolts instead of red. Max also has a high amount of health similar to that of a Dark Jedi.
Max does not play a death animation when killed. Instead, he just plays the same idle animation when he is first found, but takes on the attributes of a corpse, such as lack of collision. However if he is activated like a switch or door, he will get out of the chair and approach the room's door to exit, waiting for you to open it for him. Upon doing so, he will then wander the level, killing enemies and villagers alike. After Max has been let outside, the player can activate him again, letting them see from his view. A HUD message is also displayed reading, "It's MaxVision™!" If he is attacked by the player, he will return fire. If the player pushes Max outside instead of activating him, and attacks him, he will not fire back. If he is killed after being activated, he will freeze standing instead of playing any animation, but still becomes a corpse.
Max makes a second cameo appearance in Level 9 "Fuel Station Launch". During the final jump at the end of the level, you need to quickly snap back the mouse just before you land so you are facing backwards, which will allow you to see Max's face plastered three times on the front of the platform you just jumped off.
There is a hidden circuit in Punch-Out!! called the "Another World Circuit", which can be accessed by inputting the code 135 762 4680 on the password entry screen, then pressing A, B and Select simultaneously. The fights (in order) are King Hippo, Great Tiger, Piston Honda (Second Fight), Soda Popinski, Bald Bull (Second Fight), Don Flamenco (Second Fight), Mr. Sandman, Super Macho Man, and finally, a title bout with Mike Tyson/Mr. Dream, strangely labelled as "ANOTHER MCHAMPIONN." There is no extra content in this mode, but it does serve as a way to get to the later fights more quickly.
13 years after the release of the game, it was discovered that there is an unused, fully complete level in the code of the game. The level is named 'Stormy Ascent', and was removed because of its difficulty.
If you play as either Jin or Xiaoyu 50 times, they will be wearing a school uniform. If both of them are wearing the uniform when chosen, the fight will take place on a school stage called "Mishima High School".
Even after unlocking all 23 cheat options through the single player campaign, there is still an empty 24th space left in the cheat menu. This space is left for nine cheat options which cannot be unlocked during the course of the game. They can only be added to the menu using a GameShark. The cheat options include:
Extra Characters (800696XX 0001) Maximum Ammo (80069654 0001) Line Mode (80069657 0001) Super 2X Health (80069658 0001) Super 2X Armor (80069659 0001) Extra Weapons (8006965D 0001) Super 10X Health (80069660 0001) Multiplayer Invisibility (80069666 0001) Debug Position Display (80069669 0001)
Several of these cheats can also be activated by button codes in-game.
There is a optional hidden boss in Monstro Town named Culex, who is an homage to the Final Fantasy series. His appearance purposely breaks the style in Super Mario RPG to reinforce this homage.
To fight Culex you must go to Moleville and purchase fireworks, then trade them at the little mole's Pur-Tend Store for the Shiny Stone. Use this stone on the sealed door in Monstro Town. You'll end up in a battle with Culex, and if you beat Culex you'll get the Quartz Charm.
Culex's battle, victory, and post-battle conversation themes are (respectively) the boss theme from Final Fantasy IV, the victory theme from the Final Fantasy series, and the Final Fantasy main theme. Also, the Elemental Crystals that Culex uses are the same as in Final Fantasy and Final Fantasy IV.
In the Japanese version of Crash Bash, in Battle or Tournament mode, hold down R1 + R2 + Left + Down at the same time on the character select screen to unlock Fake Crash as a playable character.
In New Vegas, there is an enemy called the Y-17 trauma override harness. The suit was designed to make sure that the person inside would go back to the base he was stationed at in the event that he was unable to himself. However this suit has some problems. It doesn't know if the user dies, and if it doesn't have a home base, it will walk forever until it's given one.
If the player has a special perk called "Wild Wasteland", they can find odd and out of place things in the game, and when fighting this enemy you will sometimes hear them say, "Hey, Who turned out the lights?"
This is a reference to the Doctor Who episode "Silence in the Library", in which the Doctor went and found some researchers who had special suits. The suits had a function in which it would keep the user alive after he died through a link called "ghost data", and could make them speak by retaining their consciousness. One of the first people who died would repeat the words, "Who turned out the lights" over and over again since the lights inside his visor were turned off.
The main character of the game, Tamagon, appeared as a trophy in the Japanese version of Super Smash Bros. Melee. Tamagon was removed in the American version of the game but the trophy can still be found with Action Replay, complete with a translated description. Stranger still, the Tamagon trophy was removed outright from the European version of the game and cannot even be found with a cheat device, despite the fact that Devil World was released in European countries.
Should the player repeatedly shoot the lake just before battling Del Lago, the monster will burst out of the lake and eat Leon in one gulp, killing him instantly. The HD and Steam editions of the game award the player with the trophy/achievement "Don't Shoot The Water!" for doing this.
In the Normal Test Chamber 17 there is a piece of the level that's out of bounds. It was only meant to be accessed in the Advance Test Chamber 17, which is unlocked after the game is completed. It contains a momentum test with a glass panel that has a hole in the middle. This room can be accessed with cheats by typing 'noclip' into the console. It is also possible to access the room without cheats by using the 'Portal edge Glitch' on PC or it can be accessed on console and pc using a glitch called 'Portal clipping'.
Sonic Adventure is the first Sonic game to feature downloadable content, as the Dreamcast was the first ever video game console to have online capabilities out of the box. DLC ranged from celebratory holiday decorations in the Adventure Fields and a few levels, such as on Christmas and Halloween, to national ranking contests and the addition of the Chao Black Market.
Before the game was released in the U.S., Square held a "Name-in-Game" contest. A person named Kurt Zisa won the contest, and his name was used for a hidden boss in the game.
There are three unused enemies hidden in the game's code. These are CzarDragon, Colossus and an alternate Umaro. The Colossus and Umaro use the same graphics and palettes as other enemies in the game. The Colossus is fairly simple and has a full attack script, and the alternate Umaro is weaker than the original.
CzarDragon however has no script, so when the battle begins, all it does is attack repeatedly. Which is odd, as there's a line of battle dialogue for the enemy, as though it was intended to be fought. The dialogue reads: Mwa, ha ha... Humans and their desires! I'm free at last! I bring you destruction... I bring you terror... I am Czar... Prepare yourselves! Taking into account the dialogue and its likeness to Shinryu in Final Fantasy V, it seems as though CzarDragon was intended to be an optional end boss. In the Gameboy Advance rerelease, CzarDragon can be fought under its original Japanese name Kaiser Dragon. It has a unique sprite similar to the SNES design.
In the North American release of the game, upon completing God Mode, you are rewarded with a phone number (1-800-613-8840). Calling this number will play a message from Kratos, in which he congratulates the player and reveals the true fate of Ares following the events of the game, and hints at another secret that can be found.
This secret involves two statues that appear at the end of the game. If you strike them, nothing happens to tell you they are of any significance, but if you keep hitting them somewhere between 200 to 400 times, they will finally break. A cutscene with a scrambled code will appear on screen. Decoding it reveals another phone number (1-888-447-5594). Calling this number will put you through to Kratos who again congratulates the player, before being interrupted by David Jaffe, the game's director. Kratos eventually gets fed up trying to understand David's talk of video games and kills him, ending the call.
In the international releases of the game, these secret messages are not available through phone numbers due to regional restrictions. The first message is included via a cutscene with scrolling text rather than the original audio, while the second message showcases the original audio in higher quality.
As of 2022, both phone numbers are still in use for these Easter eggs.
The project director for Fallout: New Vegas, J.E. Sawyer, released a mod for the game which brings more difficulty, shifts certain NPC alignments and modifies a few character stats.
The reason this wasn't released as an official patch was partly due to its technical difficulties and difficulty curve, however it was mainly due to the development for the game and all DLC having ended.
Part of the trading sidequest involves returning a fishook to a fisherman in exchange for a mermaid's necklace. The player then returns the necklace to the mermaid who gives Link a scale from her tail in return. In the Japanese and some European versions of the game however, Link receives a pink bra instead of a necklace. This explains the mermaid's shy and anxious behavior around Link. The pink bra, most likely deemed inappropriate, was changed to the necklace in the American version and later European versions of the game.
The first 100,000 copies of the game to be printed for the Playstation contained a hidden video file that couldn't be accessed in-game. The video was the South Park pilot "Jesus vs. Santa".
