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.

отличная игра в стиле старых боевых платформеров.
bug修复,全成就,重复游玩度很好,建议大家尝试
[h1]左を狙う[/h1] [h1]正しく狙う[/h1] [h1]上を目指せ[/h1] [h1]下を狙う[/h1] 上記はコントローラーの設定変更画面にある、エイム操作周りの機能の日本語訳なんだが、まあこれを見たとおり翻訳精度はお察しである これのせいでシナリオは大筋は理解できるが所々何を言っているのかよく分からないところがあった また、メトロイドヴァニアタグがついているがこのゲームはステージクリア型なのでメトロイドヴァニアタグでこのゲームにたどり着いた人は注意 1ステージ辺りのマップはステージクリア型にしては上下左右にかなり空間が広いし、ゲームを進める毎に能力が増えていける範囲が増えていくとはいえ、でもやっぱりステージクリア型だしなあとちょっとコレジャナイ感を味わうことになるぞ というわけでこのゲームをジャンル分けするなら日本語訳がちょっと怪しいステージクリア型の2D探索アクションゲームと呼ぶのがいいだろう キャラの操作とエイム操作が分かれているような作品は私は全然こなれていないので最初はかなり苦労したのだが、コントローラーの設定を変えれば複数アクションを同時設定でき、どちらも左スティックで操作できるようにしたところ解決したので、同じように慣れていない人はこの設定をするといいかも エイム操作だけをしたいときも、ZLを押しっぱでキャラの移動がロックされるようになっているので安心だ このゲームで一番面白かったのが、最初からどこにでもチェインスタッフを足場に差してターザンの要領で移動できる部分 こいつを上手く使えば高速で移動したり通常のジャンプでは届かない足場に飛び移ったり、敵の攻撃をかいくぐって射撃したりと色々できる ただ敵キャラに接触判定があるので闇雲に振り回して高速移動すると滅茶苦茶被弾するので注意だ 個人的には接触判定なければガンガン移動できて面白かったのになあとその辺りはちょっと残念ではある ボスは基本的に攻略方法がわかれば簡単、倒し方に気づかないと一生勝てないって感じのバランスだった あ、このボスこうやればいいのかって理解できた瞬間はかなり面白かった 上でも書いたが各ステージは思った以上にマップが広く、1ステージ辺り3つぐらいの道が用意されている そのうち1つは後のステージで能力を増やした後じゃないと通れないみたいな作りになっているので、この辺りはちょっとメトロイドヴァニアっぽい要素とは言えるかも ステージ内の雑魚敵はやたら色々な所に配置されていて、むしろ多すぎてちょっとくどいなと感じた まあ少なかったら少なかったで微妙になるから結果的にはいいのかな…… ある程度アクションゲームなれしていてステージクリア型も好きな人にはオススメ ターザンアクションが要求される部分がちょいちょいあって敵も多いので、アクションゲーム慣れしていない人はやるなら難易度下げてプレイした方が良いかも 良質なメトロイドヴァニアを求めている方もコレジャナイ感を感じる可能性があるので微妙かも といった感じです
