Basically, the game is an attempt by Harper Collins to attract the D&D crowd to Warriors. The game is about a group of player-created cats from the lake Clans who go on adventures similar to those of the canon characters. The Adventure Game rules are available to read for free online, along with a tutorial campaign called The Lost Kits. An additional Adventure Game campaign is included in every book in the Omen Of The Stars arc, and in the Field Guide Battles of the Clans. As Dawn of the Clans: The Sun Trail doesn't include an Adventure Game, it is safe to assume that the Adventure Games have been discontinued.
The rules, character sheet, and a sample scenario are available for free on the Warrior Cats official website.
The Adventure Game campaigns that have been released are:
- The Lost Kits (Available for free online with the rules. Also a print version of this campaign and the rules is available officially in Barnes and Noble's The Warriors Guide.)
- Fever Dreams (Included in The Fourth Apprentice. Hardcover editions of The Fourth Apprentice also have a full-color map on the inside cover of the sleeve.)
- The Plaintive Howls (Included in Fading Echoes.)
- The Deluge (Included in Battles of the Clans.)
- Uninvited Guests (Included in Night Whispers.)
- Mission of Mercy (Included in Sign of the Moon.)
- Training Day (Included in The Forgotten Warrior.)
- Looking for Newleaf (Included in The Last Hope.)
This tabletop RPG provides examples of:
- And Now for Someone Completely Different: In Training Day, players switch between controlling the cats they created and their newly received apprentices.
- Bears Are Bad News: Mission Of Mercy has a mother bear fixing to attack the little girl for going near her cub, so the warriors have to get the girl away from the bear. This is also the only time bears ever appear in the entire Warrior Cats series.
- The Cameo: Ashfoot briefly appears in Uninvited Guests.
- Cub Cues Protective Parent: The little girl from Mission Of Mercy is having fun while playing with a bear cub...at least, until its mother shows up, growling at the girl for getting near her cub.
- Disc-One Final Boss: Uninvited Guests seems to be setting up a fox as the antagonist, only for it to be revealed that the fox is merely searching for her missing cub, and the real villain is an angry raccoon.
- Early-Bird Cameo: This is the first time a raccoon appears in the Warrior Cats series, but they don't make their full introduction until Hawkwing's Journey.
- Enemy Mine: In contrast to the canon Warriors series, the default response the Clans have to a common problem is "send out a team of player characters to save the day".
- Find the Cure!: In Fever Dreams, the Clans are all suffering from an outbreak of a mysterious illness. Feverfew is identified as the cure, so the player characters are sent on a journey to get some.
- Hopeless Boss Fight: In The Plaintive Howls, the cats can choose to engage in battle with a Twoleg. Since it's cats vs. a human, there is no way to win.
- In Medias Res: Uninvited Guests begins with the player characters stalking a fox, and doesn't explain the situation until a bit later into the adventure.
- The Medic: The Herb Lore and Medicine Lore skills make characters proficient in healing diseases and injuries respectively.
- Mr. Exposition:
- Burr of The Plaintive Howls is only there to explain what's going on with the Twolegs.
- Ashfoot, WindClan's deputy, shows up in Uninvited Guests to inform the players that two WindClan kits have gone missing.
- Non-Combat EXP: Your characters level up after every moon, and after completing each Adventure Game. Oddly enough, the rules suggest waiting a month in real time between each level up, for whatever reason.
- Talking in Your Dreams: StarClan appears several times.
- In Fever Dreams, the medicine cats all have a dream where the StarClan cats tell them about the Hill that Cries.
- In Looking for Newleaf, the player characters are visited by StarClan after they find proof that Newleaf is coming.
- What the Hell, Hero?:
- In Looking For Newleaf, if the players return with the plant but not prey, the leaders will remind them that food is as much important to the Clans as newleaf. They get the praise, all right...just not all of it.
- And in The Deluge, if the players refuse to save drowning ShadowClan cats because they think ShadowClan is getting what it deserves, the leaders will call them out on it.
- Wrestler in All of Us: Wrestling is one of the "skills" used for combat in the game. There's even a special ability (called a "knack") called "Pin" that lets you use a wrestling pin on your opponent.
