The standard progression path. Journey through instances matching legendary anime arcs (Ninja Leaf, Marine Fortress, Ice Marine). Nightmare Difficulty: After clearing an arc, you unlock Nightmare. Replaying Nightmare stages yields the best material drops and ~300 Crystal Shards per clear.
The highest echelon of PvE content. Raids feature Weather Buffs, Global Interruptions (stuns), and Walking Statues that forcibly sell your deployed units. It demands high APM (Actions Per Minute) and rewards you with the chance to pull 0.002% anomaly Secret Units.
Survival against endless, scaling waves. Used purely for checking your maximum DPS loadout capabilities and farming specific endgame threshold rewards.
A rigorous 4-phase trial testing every aspect of your composition: pure wave clear, rapid boss DPS execution, survival endurance, and speed. Primarily for very advanced, well-kitted players.
