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.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 31 → 0/day in the week after.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 21 → 0.4/day in the week after.
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 2,400 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.

like the first game but so much better. 3d really lifts up the idea. my only complaint is that most mech designs are quite boring. would love to se more non-humanoids or humanoids with catchy features like some weird back engines/wings, guns, etc
its pretty bad compared to the first one, the 2d version. i get wanting to make this in 3d but you really didn't do a good job with the building process, its way worse than the original :/
This is a very good experience for how you might build a model kit in real life. You cut the parts, you assemble to model, you apply stickers or paint it specifically, just checks all the boxes. As a Gunpla person this scratches the same itch that physically making one does for me. Given there are currently 61 kits to build ranging from quite simple to multi-layered pieces it's a good variety and as you follow the numbers up you build more and more complex things. I would definitely say it's worth the price I got it for ($14.99USD) and if you're unsure then download the demo and see if it's something you'd also like to do some of.
It's so relazxing, a great way to experince the joy of building gunplay and mecha plus it's a WAY cheaper option.
I got on steam deck and cant do everything but I loved what I can do id love to see tweaks to make it verified or even a mobile port
Juego bastante chill y entretenido, con bastante variedad de mechas.
