Evaluation

3 Days War is a free-to-play massively multiplayer strategy game that launched on April 16, 2023. The game's core design centers on recurring three-day competitive matches between dozens of players across three persistent factions, with session-based progression, hero unlocks, and rotating strategic card systems. This is a live, online-first game built to be played continuously rather than finished — there is no defined endpoint to the content experience. The game's genre tags (Massively Multiplayer, Free To Play) and structural design confirm it operates as an ongoing online service.

About this game

Background:


In 2069, humanity discovered a high-energy density mineral, the Black Stone. Countries vied for control of this resource, leading to conflicts that culminated in a global war in 2085, known as the First Black Stone War. Five years after the war began, humanity developed the Core-Gear, a giant war machine powered by Black Stone. Its immense combat capabilities had an immediate impact on the war, and within a year, the world briefly returned to peace. The world split into three major factions: the Black Eagle Union representing democracy and freedom, the White Bear Front representing the people, and the neutral Suzaku Covenant in the East. However, true peace never arrived, and the crisis of war continues...

Features:


Innovative Real-time 4X Game
A creative fusion of RTS and 4X core experience, with real-time battles and minimalistic operation, allowing players to focus more on development, strategy, and social interaction.



Grid-based strategic rules
Expansion, construction, development, and battles occur in real-time and intuitively in the "grid". A large battlefield composed of over 10,000 grids supports dozens of players to cooperate and compete.



RougeLike elements in strategy building
In the process of developing an empire, players will continuously have the opportunity to choose "pondering cards". After dozens of random three-choice selections, you will eventually build your own strategic card combination.



Heroic mechas that determine the outcome of battles
Dozens of distinct heroes drive Core-Gear to gallop across the battlefield. With the reasonable use of heroes' "active strategic skills", one can dominate the war.

Game modes:
