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 Sep 1 → 0.57/day in the week after.
Reviews, worldwide (the counter carries no country): 0.13/day in the week to Jul 21 → 1.4/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.

САМАЯ ПРОТИВНАЯ ИГРА
Richtig gutes Game, liebe die Grafik, das Setting alles passt! Gerne mehr
In [b]ZERO PROTOCOL[/b] there's a lot of [spoiler]jump scares if you run a lot[/spoiler] and haunting audio. Immersive PS1 low poly graphic style appeals on my eyes, saving system luckily forgiving on each “stage”. Only issue had with mouse aiming for stuttering / accelerating automatically quite a lot making the aiming process annoying. Couldn’t find the option to disable this movement. [h2]Final score: 8/10[/h2]

Ich werde es wahrscheinlich nicht beenden, aber es ist halt an System Shock angelehnt und macht eigentlich nichts neu oder besser. Kann man machen, wenn gerade genau Bock auf so ein Spiel hat.
good
kurzes, aber gutes game
Premières impressions : C'est plutôt une réussite sur l'ensemble de ce qu'il essaie de démontrer : * Une atmosphère lourde entre FEAR, Condemned. * Un gameplay d'action simple et solide, une partie énigme agréable * La prise en compte de la santé mentale du protagoniste est un élément intéressant dans le gamefeel * L'aspect Low poly ajoute un charme agréable, la mise en scène reste sobre mais efficace * Le challenge est présent
Great game with puzzles that are quite fun to solve.
Душно, просто много бегаешь от двери к двери и иногда на тебя нападают мертвяки. Головоломки скучные и душные а геймплей будто с мобильников нулевых. Игра ничего интересного предложить не может.
