Arknights

### **Core Gameplay & Mechanics**

* **Tactical Tower Defense:** You take on the role of the "Doctor," commanding a diverse roster of "Operators." Unlike traditional tower defense, placement involves facing direction, and each operator has unique skills (active and passive) that must be timed perfectly.

* **Class System:** Operators are divided into 8 distinct classes: **Vanguard, Guard, Defender, Sniper, Caster, Medic, Supporter, and Specialist**.

* **Base Building:** You manage an "Infrastructure" (Base) where operators work in factories, trading posts, and power plants to produce essential resources like LMD (currency) and Orundum (gacha currency).

* **Sanity System:** This is the game's energy mechanic used to enter stages. It recharges over time or can be replenished using items like "Sanity Potions."

### **Current Live Events (April 2026)**

As of **April 10, 2026**, the game is in a major peak period:

* **The "Shared Oath of Guardianship" Banner:** Launched today, featuring the highly anticipated **SilverAsh Alter (Reignfrost)**, a meta-shifting 6-star Strategist Vanguard.

* **Icebreaker Games (April 2026):** A returning fan-favorite real-time co-op event. It features synchronized gameplay without a pause button, forcing two players to coordinate strategy in real time.

* **Half-Anniversary Celebration:** This period includes increased rewards, login bonuses (like the "Prospective Login Event" currently live), and a reset of "First Clear" bonuses in the store.

* **Upcoming Limited Event:** The **"Retracing Our Steps"** event is scheduled to go live on **April 14, 2026**, taking players back to the Kjerag region with new story chapters and farming stages.

### **Technical & Ecosystem Update**

* **Arknights: Endfield:** The franchise expanded in January 2026 with the release of *Endfield*, a 3D real-time RPG. While *Endfield* features a different gameplay style (semi-open world factory building), it shares characters and lore with the original mobile game.

* **Google Play Games PC:** The original game is officially optimized for Windows, allowing for 120 FPS support, high-resolution textures, and native keyboard mapping.

* **Monetization:** Free-to-play with gacha elements. It is consistently rated as one of the "fairest" gacha games due to its 2% base 6-star rate and a robust "pity" system.

**Community Pro-Tip:** With the "Retracing Our Steps" event starting next week, veteran players are currently focusing their Sanity on farming **Sugar Packs** and **RMA70-12**, which are confirmed to have high drop rates in the upcoming event stages.
