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 10 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Reviews
Neat old school style shooter. I enjoyed the bonkers aesthetic and tone. Felt a bit like Grim Fantango meets Doom. More levels than I anticipated and there's a fair deal of challenge here to work up through if you're into playing shooters like this till you breeze through it's upper difficulty.
This game is a true hidden gem and a well-crafted piece of art with a spirit of its own. I immediately fell in love with the atmosphere present in the setting, style, and music. However, apart from that, the gameplay underneath is extremely well-designed and enjoyable. Unlike some modern old-school shooters, CC embraces the elegant simplicity of design of the 90s shooters which is something I often find missing.

Super 3D Noah's Ark got a sequel! You are Bob Boner, someone let out the crazy chickens and other animals out of the Ark. Your mission? Send them back to the shadow realm, so God can reset the universe (and make another Morbius movie). But for real, this is a fun, small, boomer shooter in a GZdoom style. The gameplay is simple but effective, I do enjoy the graphics and the level design. The music on the other hand is fantastic, some hits here for sure. Overall, I recommend this, get some calcium so your bones are strong, brothers & sisters :)
Очередная дум лайк скотобойня генетического мусора в шизофреническом антураже. Главный герой - сторонник экстремального голодания, получает задачу - провести ревизию на острове барсакельмес. -"Как же вы тут все пеpee6aлись, мерзкие квадроберы, это нужно немедленно остановить!!"- сказал герой и принялся приводить реформы по соцообеспечению местного населения в смерть. Несколько однообразная игра, сделанная с бюджетом трёх пачек ролтона и прочей бомж эстетики недорогих проектов, Нынче старый добрый doom как домашняя порностудия, каждый может выложить на его основе что-то своё не сильно напрягаясь, не роняя xyй на клавиатуру. Главное процесс, всё остальное детали. Если не пугает необтёсаное однообразие, отсутствие широкого арсенала и грубая эстетика wada на коленке, можно попробовать. А так проект исключительно для любителей подобных нутельных масс.
We need all the Calcium Agents we can get for all these Contracts.
An excellent little shooter. This is a GZdoom style shooter that focuses on well crafted levels that work in harmony with clever enemy placement and weapon management. I was impressed by three things. First, the overall design. The enemies, the environments, and the weapons all have a distinct and unusual style. It's not normally my favorite style but it's all so well put together that it ends up feeling very distinct. Second, the levels are well designed. Each feels unique and purposeful. The fact that the game doesn't overstay it's welcome helps to give each level a bit of personality. Third, the weapons are straight up fun. There are only a few weapons but each is unique. The starting "rifle" is fantastic to use and it sounds great. The shotgun stuns enemies and the chaingun bone thing tears enemies up. Even the late game rocket skull thing is useful. Everything sounds good and plays well. Overall, this is a fantastic little shooter. It doesn't overstay it's welcome and feels great the entire time you're playing it.
