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 Jul 21 → 0/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.

Calcium Chaos: Derailed -Roguelite -Casual -Cooperativo -Ação Jogo interessante, na pegada action de tiro, podendo jogar com amigos ate 2 jogadores, com um sistema roguelite, podendo upar suas armas e melhorando conforme avança durante a gameplay !! pouco da nossa jogatina !! https://www.youtube.com/watch?v=_97V0V1ukXw
After 6.9 hours I can say that it is not a difficult game, but the story and gameplay are fun. Sometimes you are unlucky with the randomizer and have bad weapons in a round. The best are the chicken, the party popper and the soap bubbles. All in all I can recommend the game but would buy it on sale. I had it twice that I pushed the opponent down with the party popper, all the opponents were defeated, but the path was blocked because the game thought there was still an opponent alive. What is mean is that when you go into the menu of the backpack the game does not pause and the opponents can continue to attack you.
Super fun o jogo para jogar com amigos, Com remote play é fácil jogar com amigos. Recomendo Muito
A very fun action roguelite with lots of combo craftting choices for weapons. Just a great game to sit back and relax while beating bad skellies.
Great dual stick shooter with sooooo many different weapons! The combination system is genius! I played for two hours and I feel like I barely scratched the surface. Haven't tried in multiplayer yet but the solo experience is already super cool. There seems to be a reasonable amount of content and I can't wait to play through it! Good job, devs!
Cool game, I want to try again!!
What a fun game, If you like twin stick shooters this is one of best this year. :)
