TEPPEN is a free to play mobile Collectible Card Game developed by both Gung-Ho Entertainment and Capcom and also published by the former. Initially teased as "Project Battle" after having early alphas sent to prominent members of the Fighting Game Community, the game is a Crisis Crossover between multiple Capcom properties that span its decorated history over the past several decades.
The story (or whatever exists of one) is set within the Land of Illusion, a world that offers the "truth", according to an individual's own wishes. Several heroes from all walks of life venture forth into it to seek what this "truth" could be, coming into conflict with one another.
Gameplay takes some cues from other popular card games such as Hearthstone: Heroes of Warcraft and Magic: The Gathering. Heroes in TEPPEN each belong to four different color classes, which represent different playstyles and archetypes: Red and Green each focus on straightforward offense and defense builds, Purple is a trickier archetype aiming to restrict enemy movement, and Black is a high-risk, high-reward class that allows for the use of tougher units which often comes at the cost of losing others or even life from the Hero that controls them.
Cards are divided into two: units that can be deployed into one of three empty slots on each player's side of the board, and actions that can result in a variety of effects like buffs or debuffs. Each use of an action card triggers a temporary stop of the game's timer called an Active Response, which gives the opponent a chance to play an action of their own and continues until the timer runs out or a player chooses to resolve it. Every card comes with a MP cost that must be met before they can be played. MP by itself can normally be gained automatically over time, but the overall pool is impacted by how many colors are in a player's deck; more colors restricts it whereas a single color leaves it intact.
Finally, each of the Heroes comes equipped with three Hero Arts, one of which must be assigned to the deck before battle and can certainly help turn the tide. Hero Arts are triggered by meeting an AP count, which is built up by the cards that the Hero plays in proportion to their MP cost (for example, a card with a 6 MP cost would make the AP count rise up by 6).

Tropes associated with TEPPEN include the following:
- Adaptational Heroism: The Tale of Amatsu no Kuni trailer depicts that the only Sengoku Basara faction that teamed up with Orochi/Yami were just the Oda clan under Oda Nobunaga, whereas Akechi Mitsuhide and the Toyotomi clan led by Toyotomi Hideyoshi were under Amaterasu's employment. In the original game, Mitsuhide and Hideyoshi were different flavors of evil compared to Nobunaga.
- Advertised Extra: The Haunted By Memories trailer really teases that Cammy, Leon, Sigma, and Zero are all going to be playable heroes due to said trailer focusing on the four of them, but instead, Zero is the only one to be confirmed as a new Hero, while the rest were just there as usable cards.
- Cammy was eventually Promoted to Playable in the Super Spooky Village update, as an EX Skin for Nero. Time will tell if Leon and Sigma will follow in her footsteps.
- Anti-Air: To counter flying creatures that certain play styles struggled against, an ability sharing this tropes name was introduced in The Devils Awaken that does exactly what you think.
- Ascended Meme: The Haunted By Memories trailer featured only one non-narrator voiceline, belonging to Zero at the saddest part of his life: the death of Iris, and it was exactly the same memetic line of "WHAT AM I FIGHTING FOOOOR!?!?", delivered by his current English voice actor in his first time.
- Brainwashing: Certain cards allow for a player to steal units from their opponents. While most of these have limitations, the legendary "Brainwash" can steal any unit, though as a legendary there can only be one copy of it in a deck.
- Brought Down to Normal: The "Seal" mechanic strips the target unit of all their abilities, leaving them with only their attack and defence before being sealed.
- Came Back Strong: Units with the ability "Revenge" return to their players deck with a buff and reduced MP cost, though this only works once. The legendary unit Nemesis has an ability similar to this, returning to the EX pocket indefinitely while gaining small boosts to it's attack and health, though without reducing it's MP cost.
- Colour-Coded for Your Convenience: Every card and each hero is divided into one of four colors, or "elements", that dictate how they fight:
- Red cards and heroes specialize in overpowering opponents by inflicting damage on opposing units and players, opening up defenses to break opponents down.
- Green cards and heroes specialize in recovery and survival, bolstering units' defenses and restoring their health to survive the opponent's assault.
- Purple cards and heroes specialize in interfering with the opponent's ability to play their cards, limiting their options and leaving them vulnerable.
- Black cards and heroes specialize in sacrificing units and burning the player's own health to unleash powerful attacks, making for a high-risk high-reward playstyle.
- Dark Is Evil: While not exclusively evil, the Black Element is the main representation for Resident Evil, and all of the heroes with the element except for Oichi can be considered either pure evil (Wesker) or violent (Nergigante and Akuma).
- Fire Is Red: The Red Element, focusing on more destructing gameplay, naturally incorporates various cards around fire, and the heroes for the element, consisting of Rathalos, the fire breathing wyvern; Ryu, who's fire is more mystical; Jill, who's more known for using explosives; and Amaterasu, the Sun Goddess.
- Magikarp Power: Growth, the main ability introduced in The Devils Awaken, functions like this, with the unit gaining Growth Points equal to the cost of additional units put on the battlefield after the unit with growth.* Once the amount of growth points is equal to the specified number, the unit levels up, resulting in a variety of effects from gaining abilities, giving other units HP, or even destroying all enemy units, with the growth cost being larger in accordance with the effect of leveling up.
- Nigh-Invulnerability: The "Nullify Damage" ability cannot allow either the hero or unit to take damage, though if their HP is reduced to zero by other means, the hero will lose or the unit will still be destroyed. Due to the overpowered nature of this ability, it is usually only temporary or, in the cases of Monstrous Virus and Familiar: Nightmare, the former forces you to lose the battle after 30 seconds and the latter is removed from the game after attacking.
- The Indestructible ability makes a unit immune to Destroy effects such as several Black cards, though they still take damage. So far, only Familiar: Nightmare and the legendary unit Amaterasu have this.
- The Veil ability makes a unit immune to being targeted by specific action cards and hero arts. However, the ability does not protect them from arts of actions that target all units or have random selection.
- Orchestral Bombing: The game's soundtrack consist of epic orchestral arrangements of each playable character's theme.
- The Paralyzer: The Halt status temporarily stops a unit from attacking or countering for a certain amount of time, resetting their attack progress once the effect expires.
- Powered by a Forsaken Child: The "Ascended" mechanic introduced in The Force Seekers expansion involves placing a unit on top of another unit already on the field, sacrificing the other unit in order to activate another effect, usually powering up the Ascended unit, though other effects include dealing damage or destroying an opponents unit.
- Sidelined Protagonist Crossover: Usable cards and cameos notwithstanding, Sengoku Basara is (so far) the only franchise to not have any protagonists nor main characters as heroes with it's only hero being that of Oichi, who is rather a supporting character in the series.
- Status Buff: The Resonate ability acts like this. Whenever the player uses an action card, it triggers Resonate. This usually boosts health or attack, though it can also cause damage or, in cases such as Devil Hunter Dante and Forlorn Protector Lucia, transform the unit, with the former becoming Devil Trigger Dante and the latter Devil Form Lucia.
- Super Mode: Some units, when specific conditions are met, transform into more powerful units, such as Dante, Nero and Lucia transforming into their Devil forms, and Akuma transforming into Oni.
- Technicolor Magic: The purple element mainly revolves around more supernatural abilities, with the two founding heroes for the element, Dante and Morrigan, being demons of significant power. Zero, introduced later, is not a demon in the traditional sense, but is the progenitor of the Maverick Virus in his home series.
- Title Scream: Every time you touch the screen to start the game, the last character you played as in Chronicles, Practice, and/or any of the modes on the Battle screen will shout the title. And yes, this even includes the characters who only speak through animal noises!*
