鋼鉄戦記C21

C21 Steel Battle Chronicles is a free-to-play Action MMORPG developed and published by CyberStep, Inc., released on October 14, 2020. The game is built around ongoing online multiplayer, continuous robot part collection, and exploration of "new planets and areas" — language that signals an ever-expanding live game rather than a fixed, completable product. Its genre classification (Action, Massively Multiplayer, RPG, Free To Play) further confirms this structure. MMORPGs of this type are designed by nature to receive continuous content updates, seasonal events, and new areas on an ongoing basis rather than concluding at a defined point. While the 50 developer news posts available on the store could not be individually categorized for content, the sheer volume of posts over the game's lifespan is consistent with the sustained update activity typical of a live online game. This is not a game that is ever intended to be "done" — it is a live service experience designed to evolve indefinitely.
