“As a certified computer enjoyer, I've loved my time with Grey Hack so far. It's not going to be a substitute for pentest labs nor official trainings, but it can introduce you to some high level concepts and give you a…”

“Spectacularly good. I've been learning about penetration testing and trying to get more proficient with Linux, and am finding the game really helps me put what I'm learning into a more real world context in a fun way.…”
“Grey Hack is one of the most unique games I’ve ever played on Steam. 10/10 Very Underrated!!! At first, it looks intimidating, especially if you know nothing about coding or Linux-style systems, but that’s exactly what…”
“Great game, now I can get my fix for hacking computers and stealing peoples' credentials without going to prison! Haha I kid. It's pretty realistic for basic pentesting, at least what I've seen so far - I was surprised.…”

“I've enjoyed the game so far. You can clearly see it's still in development but the entire game interface is very immersive. I've run into a few minor bugs but I was able to get around them and the developers seem to…”

“Very good game to learn and have fun. Grey Hack is a hacking simulation game that sits on a sandbox persistent world with almost unlimited IPs to connect. Some IPs can be from players (in the persistent mmo mode). Where…”
“as real as a game can get while still being fun to play. the environment is a simplified unix-like operating system and the tools are simplified versions of the real thing. the multiplayer feels great and, for me, it's…”

“If you get this game, know that it has an insane learning curve, you'll learn FAR more from the community on Discord than any in-game resource, and it's mostly geared for PVP instead of PVE. You'll want to have a…”
“i didnt like this game when i first started playing it. I didn't know how linux worked. Didn't know how GreyScript worked. I found it difficult and quite frankly, frustrating. But instead of giving up - which i sort of…”

“I gave it a chance, hoping the early reviews about the bug soup had been adresssed. Nope. Game is too broken to even pass the tutorial level. Anyone without real Unix experience is going to be totally lost. There is no…”
“9/10 Just started, Hoping to run into less issues - Why don't notes update when saved instead of creating an updated copy? - Why are files copied when dragged rather than moved? - Why can't I navigate using cd / (which…”

“I went into this game with zero knowledge about Linux. The tutorial is rather short, but there is a whole Manual to read (with a search function) that helps you figure out what to do next. The game is quite interesting and I still have lots of things to learn. Edit: Ok, this…”
