Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Just meh its partially a visual novel which I did not want in this game and combat level on a mobile game.
戦闘面以外の要素は面白いが戦闘面がすべて台無しにしている
The game has FANTASTIC POTENTIAL only to be stuck behind meaningless updates, and multiplayer that seems like the only reason this game has been in development for SIX years, theres still not much story. The customization is great though! Its just that there isnt much to do.
Mech designer part is truly unmatched, but the gameplay just isn't that fun.
다 좋으나 당신들이 한국과 미국을 혐호한다는거는 개속 기억할것 입니다.
Not saying anything mind blowing here. What you can do with the customization visually is astounding. However, you're actual options for function are rather limited. A pretty small and boring line up weapons. This extends into the gameplay which is just the most soulless thing. Boring flat level design. Uninteresting bullet sponge enemies. You can design the most badass looking mecha, but the game will never let you feel like badass playing it. And the less said about the story the better.
Hate that the devs abandoned this game
