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.
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.
About
Note: No Gen AI was used.
Our planet is under attack from the Star Spores, and they've warped life on Earth into ferocious uber-bugs.
Even worse, a nasty alien has made its new home directly attached to your head.
But it's not all bad news - your new best friend has provided both the strength to fight back against the mutated horde, and control over a weapon that can tip the balance of the battle in humanity's favor: the ChainStaff.
As you traverse the surreal landscape, you'll encounter your fellow soldiers, stranded in harsh environments. Do you rescue your comrades, or listen to the alien voice in your head and harvest them for upgrades?
If you can persevere and defeat the Star Spores, perhaps you can save everyone…including yourself.


Hurl it as a spear and slice aliens in half. Throw it to the ground as a shield to stop incoming attacks. Grapple and swing on just about anything. The transforming ChainStaff does all this and more, and all with one button, it’s all up to you.

Pounded to mush, stabbed through the heart, sheared in two. Prepare to meet your doom in a myriad of disgusting ways. All deaths are avoidable, but some dangers may require special strategies.
The game features around 6 to 8 hours of gameplay on the first playthrough.

The creatures of Earth have been mutated by aliens: you’ll come across dozens of unusual creatures, and once you get past those, you’ll have to fight against screen-filling monstrosities.

Stranded soldiers dot the landscape of ChainStaff. You have to choose whether to rescue them or devour their organs; each option has unique benefits and will lead to different endings.

Mist trails around rocky crags.
Wind blows over icy, moon-lit hills.
Water streams down mossy cliffs.
Fully hand-drawn art immerses you in a living world inspired by album covers of the 70s and 80s.

Scorching riffs and peals of thunder. Pumping beats drive you ever forward.
Rock out to the classic metal soundtrack by the award-winning composer Deon van Heerden of Broforce and Warhammer 40k: Shootas Blood & Teef soundtrack fame. There’s some lighter interludes with 70s synth, catchy melodies, and even some cowbell. Now it’s back to the heavy tracks, where it’s time to bang your head while smashing skulls.

开二周目有BUG,不知道有没有人和我一样的情况。5、6、7、9关无法解锁。
武器になり、盾になり、移動手段にもなる「チェインスタッフ」を操って地球を侵食したエイリアン軍団と戦うのが面白かった。ヘヴィメタルなサウンドとビジュアルもいい。巨大なボスとの戦いではチェインスタッフの機能をフルに生かして独自のギミックに立ち向かうのも魅力の一つ。 日本語訳もついているが、こなれていないのと一部の文字(ステージセレクトでの)が見れなくなっているのが惜しい。
精品!!!

敌人设计很有意思,有魂斗罗那味。 但是关卡设计一坨,几个场景重复好多遍就是一关,没有什么记忆点。 略显无聊,但是尝鲜还可以。
好
отличная игра в стиле старых боевых платформеров.
2d 횡스크롤 런앤건 게임 인류의 기술을 사용할것인가? 자신의 벌레능력 진화시키느냐? 선택 포자를 먹어야 다음 지도가 열리는데 9맵 안열려서 찾는다고 애먹음 튜토리얼 부터 난이도 까지 깔끔하게 재미있는 게임 근데 그래픽은 벌레인데 징그럽진 않네
good
找不到二段跳,不知道藏哪了,第九章图不知道怎么解锁,剩下的支线路线都要二段跳,牛逼
bug修复,全成就,重复游玩度很好,建议大家尝试
