About Phantom-OS


Phantom-OS is a physics-infused strategic hacking simulator where you will put your skills and wits to the test.

You play as Kyle Hastings, a capable programmer with a knack for hacking. Having dropped out of college to focus on your newfound passion, you now live a double life: a freelancer by day and a gray hat hacker by night. But little does Kyle know, his life is about to take a major turn when he installs a strange operating system: Phantom OS.

UNRESTRICTED ACCESS (NO SCRIPTED LIMITATIONS)
A core philosophy of ours is a “no scripted” approach to player actions. You can (eventually, given your skill as a hacker) gain full control over every device in your network, delete, break (as in physically, with a hammer) any computer you can get your hands on.

WINDOW-BASED OPERATING SYSTEM
A familiar concept to almost everyone, your computer behaves like - what else? A real computer. Run programs, create, move, and delete files organically, and given the special arsenal of tools at your disposal, infiltrate into other machines to steal data, brick devices, or spy on your targets.

FULLY SIMULATED NETWORKS
Every computer, from those you target to the ones you own, are fully featured internet-connected devices, able to communicate and transfer files between one another. This happens via in-world routers and relays making up the network.

PHYSICS BASED ENVIRONMENT
Your computers, like your environment, are real in-world objects. You can move, interact with, and modify them for your own needs. Make your hacker den your own.

EMERGENT GAMEPLAY
The way you tackle missions depends on your approach.
  • Go in person and attempt to get physical access to your target.
  • Remotely from your secured network
  • Social engineering

FACTIONS
As you make a name for yourself, you will discover that you are not alone. Multiple other hacker groups will notice your actions and either take a liking for it or attempt to shut it down. Balance your influence with social opinion on your actions, maintaining a delicate balance to not risk detection.

LIVE YOUR LIFE
The world waits for no one, not even you. Opportunities come and go and it's your job to make the most of them. The game features a full day/night cycle with events and opportunities becoming available during certain times of day, so plan and manage your personal life and schedule accordingly.
Your surroundings affect you as much as you can affect them. Learn your town and its networks, opportunities, and exploit them to achieve your goals - be it fame, money, or connections.

BEYOND/HOPEFUL
Given the early-access state of the game and our very small team (2), we plan to continue working towards achieving our final vision for the game, past the stuff mentioned above. This will include:

MILESTONE 1
  • Procedurally generated hacking opportunities (events, scheduled PC uptime, rival hackers' actions, etc.)
  • Currency, inventory management, upgrade systems
  • Leaving the apartment - outside city content: locations and activities

MILESTONE 2
  • Multiplayer V1 (hacking only - players can help each other from their apartments)
  • Adding roleplay elements (NPC interactions)
  • Game balancing
  • Modding support

MILESTONE 3
  • Expanding roleplay elements (reputation system, branching story)
  • Diversification of missions, quality of life Improvements
  • More content (larger city, more missions)
  • Multiplayer V2 (fully featured coop and group missions)

"Phantom-OS" is an abandoned Early Access attempt to make a "desktop simulator" (yawn), combined with a little asset flipped Unreal engine window dressing as you have to get out of bed and walk to your computer. What that adds to the unpolished, buggy and pointless experience is beyond me. What do you do in the game? Well, it's got nothing to do with hacking obviously, it's just a text based desktop simulator puzzle game, but it's incomplete and abandoned, for pretty obvious reasons. Says a lot about how bad a game is that not only did gamers not want it, but the developer didn't want it either. The developers abandoned this 1 year and 10 months ago. It will never be completed. This unfinished game is just polluting Steam and making it harder for gamers to find genuinely, completely made games. The game graphics look better than you might expect, but that's just because it looks like some or all of them are "borrowed" from asset stores or wherever. Gamers can tell... and it comes across as insincere. There's also the old adage that those who lack the budget and talent to make their own game assets usually lack the budget and talent to do the rest of the job of game develo…

Game says FTP but after doing one single task, I got the "YAY DEMO'S DONE!" with literally no option to do anything. Maybe it's user error, but it was probably the most pointless "demo" I've ever played - made even worse by the fact that it wasn't described as a demo.

Really cool idea! First of all the is a lot of potential in adding cool stories and random side quests and gigs. I think that should be the main attraction for this game. However in order for this part to shine you need to find a way to make it easier/clearer on how to hack stuff. Me, I am a programmer and know my way around things like Linux and also how some of the more know hacking strategies work, but if you want to make this for a wider audience the you need to find a way to make it not easier for non technical players. Really good job with this demo and I hope I see this released :D

This game has a ton of potential, and I have high hope for whatever the creator thinks of. 100% recommend.

Fantastic introduction. I would love this to be a finished game. Exactly the niche approach I was looking for in a game lately.
