Under Oath

Can a Turn-Based RPG Deliver Real-Time Pressure?

Under Oath is a mobile role-playing game that combines anime-style visuals with turn-based combat mechanics designed to test your strategic reflexes. Developed by Bilibili Games, this title positions itself as a narrative-driven experience where you serve as a protector of individuals under your charge, facing life-threatening dangers through a series of scripted encounters and open-world exploration.

Core Gameplay Mechanics

The game operates as a standard massively multiplayer online role-playing game (MMORPG) with a fixed isometric perspective. Navigation relies on a virtual directional pad located on the left side of the screen, or you can tap on mission objectives to enable automatic pathfinding. Quests are distributed across various cities and hubs, each offering experience points, gear upgrades, and new recruitable allies as rewards.

Combat unfolds in a turn-based format with a strict time limit per action. Each character in your active party possesses four standard attacks plus one special ability designed for high-damage output. The timer forces quick decision-making—you cannot pause to consider options indefinitely. The visual presentation during battles is rendered in a high-contrast anime art style with particle effects for abilities and environmental interactions.

Party Composition and Progression

Your active squad is limited to three characters at any given time. Additional heroes are unlocked through two primary channels: the story campaign mode and a standard gacha system. Strategic balance is required when assembling your team, as each character has distinct strengths and weaknesses that directly affect combat outcomes. The game encourages experimentation with different synergies to counter specific enemy types or encounter conditions.

Progression follows a linear path through the main storyline, with side quests and daily challenges providing supplementary rewards. Equipment can be upgraded using materials obtained from missions, and character levels increase through experience points earned in combat. The gacha system introduces random hero acquisition, with rates and pity mechanics typical of the genre.

Audio and Localization

Under Oath features full voice acting in both Chinese (Mandarin) and Japanese, performed by professional voice actors associated with the anime industry. The soundtrack consists of orchestral and electronic compositions that shift between exploration and combat phases. Text localization is available in multiple languages, though the original voice tracks remain in their source languages regardless of the selected interface language.
