Arknights

Q: What genre of game is Arknights?

**Arknights** is a strategic **Tower Defense RPG** with gacha mechanics. Unlike traditional tower defense games, you deploy "Operators" (characters) with unique classes, skills, and stats. It emphasizes tactical planning, timing, and squad composition over pure reflexes.

Q: Is Arknights free-to-play friendly?

**Yes.** Arknights is widely considered one of the most F2P-friendly gacha games. * All content can be cleared with low-rarity (3★ and 4★) units. * There is no PvP, so there is no "pay-to-win" pressure. * The game provides free premium currency (Orundum) through daily/weekly missions and the Annihilation mode.

Q: Who is the Doctor?

The **Doctor** is the player character and the tactical commander of **Rhodes Island**. You start the game with amnesia, having just been rescued from a sarcophagus. You are a brilliant strategist and a researcher dedicated to finding a cure for Oripathy, but your past is shrouded in mystery involving a dark, ruthless history.

Q: What is Oripathy?

**Oripathy** is a terminal, infectious disease caused by exposure to Originium (a high-energy mineral). * **Effects**: It crystallizes the body and grants magical powers called "Arts," but eventually kills the host. * **Social Impact**: The "Infected" are discriminated against and persecuted in most nations, driving the central conflict of the story.

Q: Who is Amiya and why is she important?

**Amiya** is the public leader (CEO) of Rhodes Island and the main heroine. She is a Cautus (rabbit traits) / Chimera who is deeply infected with Oripathy. She is the successor to the late Theresa and fights to build a future where Infected and non-Infected can live together. She is the only 5★ Operator given for free who can be promoted to a 6★ status later in the story.

Q: How does the Gacha system work?

The gacha (Headhunting) uses a currency called Orundum. * **Rates**: 2% for a 6★ Operator. * **Pity System**: If you don't pull a 6★ in 50 pulls, the rate increases by 2% for every subsequent pull until guaranteed. * **Standard Banners**: Rotate regularly, allowing you to buy specific 6★ operators with "Distinctions" (gold certs) in the shop.

Q: What is 'Sanity' in Arknights?

**Sanity** is the game's stamina system. Every stage requires a certain amount of Sanity to play. It regenerates over time (1 point every 6 minutes) or can be refilled using items (Sanity Potions) or Originite Prime (premium currency). The lore implication is that the Doctor needs rest to maintain mental clarity for commanding battles.

Q: What is Arknights: Endfield?

**Arknights: Endfield** is an upcoming 3D real-time strategy RPG spin-off set on a different planet (Talos-II). It features new characters and gameplay mechanics (base building, open-world exploration) but shares the same worldview and deep lore as the original game.
