Prices
The United States storefront in every case, so this compares stores and not countries.
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 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.

Zero Tolerance on PC is one of those “yeah… maybe it was better in my head” situations. I remembered this thing as some kind of hidden gem from the Genesis/Mega Drive days, tight corridors, creepy vibe, that intro going way harder than it had any right to, feeling like you were playing something futuristic as hell back then. And to be fair, on console it was kinda revolutionary for its time. Cool concept, solid atmosphere, gameplay that actually worked… just at like 10 FPS (back when people weren't pus**es about that). So you’d think the PC version with turbo mode fixing the speed would save it, right? yeah, no. It runs smoother, sure, but now you actually feel how awful the controls are. It’s like trying to steer a shopping cart with a broken wheel while everything wants to kill you. What used to feel tense now just feels clunky as hell. You’re not fighting aliens, you’re fighting the game itself. And not in a fun way believe me. It’s still got that nostalgic charm, I’m not gonna lie. If you’re really into retro stuff, you can squeeze some enjoyment out of it (with a D pad controller). But if you’re coming in fresh? just leave it in your memories, or someone else’s. 7/10 for nostalgia, but man… this aged rough.

My friend, Tony Ramos, aka Weasel, told me about this game and i tried it out, as we were both in call and he told me all the tea of all the characters and developers as he watched me play. Thank you BIG T I'll never forget you! BTW the controls for keyboard is x, c, and the arrow keys!
5/10 It was a great game at a time, beat it myself at least 3 times. But now it's just too outdated. Controls are terrible, graphics hurt your eyes and it is really hard to navigate. Nostagia alone simply ain't worth it. Just watch a playthrough on youtube, get your relieve and move on with your life.
Pecetowa wersja gry robiona była po taniości jakby ktoś chamsko odpalił tę grę na emulatorze tryb turbo to dosłownie jakby ktoś dał na emulatorze segi mega drive przyśpieszenie na 200% nie da się w to grać ponieważ przeciwnicy poruszają się za szybko i sterowanie na klawiaturze czy nawet padzie jest zwyczajnie za wolne i nie precyzyjne można szału dostać próbując w coś wycelować gra nie ma żadnych usprawnień graficznych! na konsoli mamy fajny filtr retro ekranu kineskopowego a tutaj też jest filtr ale wygląda on tak niewyraźnie że nie ma sensu jego używać kolejna rzecz to to że nie otrzymujemy zero tolerance underground czyli darmowego dodatku z nowymi poziomami! nawet takie rzeczy jak dodatkowe menu z fajną muzyczką co dodaje klimatu tutaj też tego nie ma tak więc radzę się trzymać z dala od wersji na steamie
jogo lindo e maravilhoso,nostalgia <3
Remediable classic, but the console ports of the of released are way more superior. Which the console ports are titled as Zero Tolerance Collection which featured the unleashed sequel, but the digital PC versions on Steam or GOG are just a lazy emulation port, if i wanted to play the emulation port, i play the Genesis/MegaDrive port! As much as i'm a PC gamer, all they do for Zero Tolerance is release or update this version toe the Zero Tolerance Collection like how they did on the console ports! But as of now on Steam or GOG, i don't recommend this port!
Лучший 3D-шутер, выходивший эксклюзивно для Sega MD, игра очень приятно управляется и сносить врагов в щепки одно удовольствие. Игра даст фору даже Doom'у. Ведь в ней можно прыгать, приседать, остаются следы крови, стекающей по стенам, анимированы трупы врагов: у кого-то льется ручьем кровь, убитые крабы двигают лапками и их можно поджечь огнеметом, некоторые стены осыпаются от выстрела, взрываются экраны мониторов, в общем интерактив! В данном порте есть два режима игры обычный и турбо (рекомендую турбо), но данный выбор почему-то предлагается только если запустить игру из библиотеки Стима. С иконки на рабочем столе запускается обычный режим, что досадно. Рекомендую к приобретению для коллекции лучших 3D-шутеров всех времен!!
Что тут сказать играют сволочи на ностальгии! Могли хотя бы какой-нибудь вменяемый фильтр поставить, чтобы каши из пикселей не было. На эмуляторах можно настроить картинку получше. Игра очень атмосферная и тормозная выжимающая все соки из мегадрайва. Тут наверняка тоже эмулятор древний типа Gens под капотом. Ностальгии уже не чувствую даже если постараться, все это как из другой жизни.

It's a very nostalgic, laggy, mess... but I still love it
