Game development requires the use of engines, some are self-developed, some use mature existing solutions, and others modify existing solutions. Some players are curious about what engine Arknights: Endfield uses. Nowadays, many secondary games in development use the Unity engine and Unreal Engine, each with their own advantages. After verification, it is known that Endfield uses the Unity engine, which is commonly referred to as the Unity engine.

The game is developed using the Unity engine, featuring a 3D modeled action role-playing game, and its infrastructure part can switch to an overhead view. The developers made significant modifications to Unity, allowing it to support more game content. It can be said that basically, the entire underlying rendering framework and upper-level rendering pipeline are self-developed.

It can be understood this way: only the Unity architecture and editor, tools were retained, while the internal core components and contents were restructured, especially the graphic rendering part of the engine was completely overhauled, making the processing of game components more efficient. Additionally, the graphics API level was also restructured to meet the performance requirements of the game.

A notable optimization is in the seamless map aspect. In earlier technical tests, loading bars were required when switching between certain levels. Later, scene reconstruction and the underlying technical framework, toolchain, new terrain handling methods, virtual texturing technology, and seamless loading technology were developed, improving the efficiency and smoothness of loading and scene transitions.

In addition, there are also proprietary technical solutions for lighting and shadow technology, factory construction, etc. For the game's audio effects, a professional team was formed, recording real objects and reproducing them in the game.

The above is an introduction to what engine Arknights: Endfield uses. It is built using the Unity engine, but it can be said to be heavily modified, retaining only the Unity architecture, editor, and tools, while many other core components and production processes have been restructured, especially in the area of graphical rendering. What engine a game uses is not the most important thing; the key is whether the game is fun to play or not.
