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 25 → 0.57/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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
You are a British soldier during WW1, trapped in an endlessly looping trench. To get out, you will need to reach the final trench by identifying any anomalous changes that were not there before.

Carefully inspect the trench — things may not be as they seem!
If you spot an anomalous change, you have something to report. Go Left!
If you have nothing to report. Go Right!
Shellshock is a short anomaly hunting experience (up to 30 minutes) inspired by liminal spaces and psychological horror. If you correctly Identify any changes in the trench you will progress to the next loop. If you do not correctly identify a change or you think there was a change when there wasn't, you'll go back to trench 0 and start again. Your goal is the reach the final trench and escape.

There is nothing to report in the first trench.
Walk through all following trenches and look for changes.
Take your time. Pay attention.
Some changes are easy to spot; others are more difficult.
The trench is short, but the differences are randomised in each loop — sometimes there are no changes at all.
Once you are sure whether there is a change or not, exit using the appropriate door.

Playtime is around 10–30 minutes depending on difficulty.
Difficulty level determines which trench number you must reach to escape.
Simple controls:
WASD – Move
Mouse – Look
Shift - Run
CTRL - Crouch
Controller supported
Anomalous changes in the trench will only occur once.
Anomalous changes will reset once all anomalies have been identified.
Anomalous changes can be manually reset from the options menu.
Some changes may include upsetting or graphic content related to themes of war and injury.

一个没什么游戏性的找异常游戏居然敢把成就设定成不能失误一次,异常设计的也没什么技术含量藏的一个比一个难找,纯粹是骗2小时退款的差游戏
a really fun game, me and a few friends played it together and the anomaly's where cool and leaned slightly into horror. we also ended up naming the three soldiers that where with us , Jorky George, sitty Steve, and weedy Wendy and the occupant for the fourth one that showed up rarely. my only criticism for the game was in the find them all I wish there were no repeats unless you failed and was sent back to trench 0 cause I was at trench 50 with 3 anomalies left and all I kept getting was repeats which really dragged out the experience. though 8/10 will comeback to play the update.
The trenches were already horrifying enough... Shellshock takes the anomaly genre and puts it somewhere that already feels like a nightmare before anything strange even starts happening — the trenches of the First World War. I really enjoyed this one. Walking through the same muddy, battered trench again and again creates a surprisingly oppressive atmosphere. There’s something particularly unsettling about the WWI setting, and as things begin to change it starts to feel less like you’re simply walking through a trench and more like you’re trapped inside the mind of a soldier who has seen far too much. The name Shellshock is very fitting. The repeating trench, the bodies, the sounds of war and the increasingly disturbing things you encounter give the whole experience an almost fever-dream quality. It plays nicely with that line between something actually being wrong and the possibility that your soldier is simply losing his grip on reality. It’s a short game, but I actually think that works in its favour. It doesn’t drag the idea out until it loses its effect. I enjoyed my time with it, liked the WWI setting immensely, and found the darker anomalies genuinely effective. For the price, this is an easy recommendation from me — especially if, like me, you have an interest in the First World War. Keep your head down, Tommy. Something in this trench isn't right.
第一次世界大戦中の英国兵士として、無限にループする塹壕に閉じ込められるウォーキングシミュレーター。 脱出するには、以前にはなかった異常な変化を特定して、最終塹壕に到達する必要があります。 今までたくさんの異変探し系ホラーが発売されましたが、本作は今までに感じたことのない不思議な感覚を味わうことができました。 第一次世界大戦が舞台ということもあり、異変は基本的に戦争に関連したものが主となります。 異変を見つける度に胸が苦しくなったり、銃弾が降り注ぐ恐怖に直面したりと、恐怖の系統が今までの作品とはだいぶ異なっています。 一部の異変には、戦時中とは思えないほどの美しい光景や景色が広がったりして、そのアンバランスさもまた、どこか不気味な感覚を覚えました。 一番簡単なモードでのクリアは1回約30分くらいですが、短い時間の中でもかなり濃密な体験をすることができると思います。 エンディングロールも制作者様の戦争に対する思いなどを受け取ることができ、戦争について考えさせられる内容となっています。 ゲームのテーマはとても重たいものではありますが、システム面がとても充実していて遊びやすい作品となっています! 3つの難易度から選択することができて、初心者さんも安心して遊べると思います。ただ、異変のコンプリートは結構高めに感じました。 350円とは思えない濃厚な体験をしたい方は、ぜひ一度遊んでみてください!
[h1] Krótka, dobrze wykonana i przyprawiająca o dreszcze gra o anomaliach [/h1] [h3]Shellshock to nowiutka gra przedstawiająca głównego bohatera ( nas ) przechodzącego przez trenche, ( czyli rowy po polsku xd), które prowadzą przez okopy podczas | wojny światowej. Przechodząc tę grę, na samym początku, widzimy teren okopów, który powinien być za każdym trenchem taki sam jak jest pokazany na starcie. Jeśli coś się zmieni np. obrazek, ktoś zniknie lub po prostu będzie inaczej niż powinno - jest to anomalia, jak nic się nie zmieniło - nie ma jej. Jeśli zauważysz anomalię, idziesz na lewe drzwi, jeśli jej nie ma to idziesz na prawe. Jak się pomylisz z anomalią lub jej brakiem, zaczynasz od początku. Osobiście grając w tą grę nie bałem się zbytnio ale miałem duże ciarki. Spodobała mi się tak bardzo, że aż ją splatynowałem (3 osiągnięcia btw) Większość gier o anomaliach ma ten sam motyw jak tu, czyli przechodzisz przez poziomy z anomalią lub bez niej. Prosty, przyjemny symulator chodzenia :) Polecam każdemu kto lubi gry typu anomaly.[/h3]
As someone who loves anomaly games and is a huge history love, Shellshock was a must play the moment I saw Caseoh play it (although his stream crashed halfway through the game due to his internet lol) and for the quality of the game, 2 quid is a steal and really shows how it was like in the trenches while also making it fun through being an anomaly game. One thing I really disliked and thought ruined the game was the [spoiler] Backrooms anomaly [/spoiler], while yes and anomaly game is supposed to have something different to guess on, I really felt it ruined the overall WW1 trench feel which the other 39 anomalies don't really do. Asides from that anomaly I think the others were really well thought out and still makes the trench feel like its in the correct time period but having obvious differences (sometimes a bit too obvious making it pretty easy). For full completion it took me 76 minutes making the game very short with possible replay value after a while, overall 8/10. R.I.P to all the soldiers who died during WW1, may these heroes forever be remembered.
Spot the difference with a WW1 theme! This game although short is fun and could be expanded upon. It's essentially a 'spot the difference' game with some anomilies being trickier to find than others. I'd like to see some combat, even minor, added for a more immersive experience and perhaps the use of tools and or weapons to solve puzzles would be great. More NPC variants would be good to see too, but I'm sure many changes and additions will be done in future updates. Just an FYI for the team, the 'most brutal war in history' was WW2 which created a death toll between 70-100+ million. This does not detract from the lives lost in the First World War, simply that when a statement is made it ought to be accurate.
