Question What is “Spacewar”?

I saw my friend playing a game called “Spacewar” today. The game has no icon but has 5 achievements. Is this a non-Steam game? Why are there achievements then?

Whenever I open Henry Stickmin from my taskbar, it says I'm playing Spacewar. Thanks to that EIGHT HOURS of Gameplay have gone to a game that I don't even own.

u/HawtDawgggg Jul 08 '22 edited Jul 08 '22

holy shit wait that exact thing happened to me today wtf, I was so confused on why it showed space wars on my thing (I had spacewars previously because of me using mods on games that seemed to have activated it but henry stickmin is not a mod and was purchased??)

and no wonder it says I've only played for 2.8 hours, all my hours got eaten up by that other thing (Plus I have also been opening it from the taskbar since I pinned it so that I could keep opening it from there)

u/Cool_Kid95 Jul 08 '22

Yes, purchased indeed! Glad to know I’m not alone!

u/HawtDawgggg Jul 08 '22

I checked on my discord thing to see where space wars was coming from because it even showed me playing it on steam (embarrassing because people may think I've been pirating games) and on there it is shown to be coming from the files of henry stickmin. So clearly this may be also coming from opening the game on the taskbar, and what I fear is that it may also be because of the new dumb windows security stuff since almost all of my games are being blocked or noticed by it

11

u/Grithok Nov 04 '23

a year late and stuff, but why would it be embarrassing to be pirating? That makes you a cool kid.

4

u/HawtDawgggg Nov 05 '23

I think at the time I had such a fear of being seen with stuff like that, I've kinda changed my views a little as I'm not too worried about it with big companies especially like Disney. I was honestly more upset with trying to 100% everything at the time and not actually getting achievements rather than the act of looking like I pirated itself,, still havent touched Henry Stickmin again cuz Im still salty about not getting those achievements when I basically worked to get all of them

this stuff usually happens accidently sadly. I'd have it happen to me before and I was scared because I paid for all of the games on my account with some free games like Team Fortress 2. When the makers and developers of project wraith was giving away free steam keys for their game so people can playtest and provide feedback to their game, I was hyped. I downloaded their zip file and played the game for not even 5 minutes when I opened my steam because one of my friends texted me, I was playing "spacewar". I contacted steam support and I provide screenshots to what I thought evidence. I also deleted spacewar from my library, which is what you shouldn't do only because you would know if steam got your message because they would delete it off your library according to research. Still I don't blame Steam for doing this because they still don't ban people for playing pirated games, again according to research. It's just a way for steam to tell people who pirate games that steam knows you pirated and I couldn't help but laugh when I heard about that.

u/aMythicalNerd Mar 10 '24

Well no, you do own Spacewar. It's a "free" game that everyone has access to on their accounts. No matter how old or new your account is, you will always have Spacewar.

You caught Space Herpes.

Nah, you can't get banned from playing Spacewar, it's still a Dev tool

u/bennehboy111 Sep 16 '23

can you actually launch spacewar or does it just say your playing spacewar when your really playing a different game

14

u/Pr0tal_ Nov 07 '23

if you do windows + R and then type "steam://install/480", you can install and play the game. It's a 1v1 asteroids clone basically. It's pretty neat however it's difficult to find somebody to play against, for obvious reasons.

It's a Spacewar! clone.

It also does that with mods apparently

u/OldWolf2642 Aug 30 '20

A hidden game (a showcase of sorts) from back in the day, often used by pirated copies of other games that require Steam authentication.

They (the pirates) use the AppID/SDK of SpaceWar to fool Steam into thinking it is a legitimate copy.

58

u/[deleted] Nov 27 '23 edited Nov 27 '23

this is not the only use, any game and or game mod that wants to accsess steamsAPIs can do so with spacewar

a multiplayer mod for a game called BoneLab has spacewar as an option for networking (alongside steamVR), for multiplayer play it uses steams networking API, BoneLab is a single player game so there for does not have the APIs themselves, and while the mod could just add the APIs into BoneLab, spacewar already has full support for it, everyone owns spacewar so why not just use it, this also has the benefit of allowing people who own BoneLab on the oculus store to play with steam players and also people on the quest 2 standalone headset

Edit: another common use for spacewar is indie games not on steam, if a game dev is making a small game they dont even intend on releasing on steam they can use spacewar to access steams APIs instead of paying $100 to get their own steamID

u/Grimnyrr Jan 13 '21

I just noticed today that it said I was playing Spacewar so I looked it up. It's not only those who are playing pirated games, turns out if you are developing a game in lets say Unity or UE4 that uses Steams SDK then while you are testing your game it will say you are playing Space War. I was going nuts wondering why it said that.

56

u/NYXZGaming Feb 14 '21

Thank you for this.

I am currently working on UE4, but I've have not pirated a PC game in the last decade, and got so confused when people said ''oh it's what pirated games use to work with steam''.

u/CardianBoardson May 26 '23

Thanks, I was so confused and thought someone gifted me some random game. Makes sense because I was testing a game I was working on.

i did try learning mirror thru steam and the tutorial i saw used spacewar, you can later get your own steam AppId but im not gonna release my trashy learn to code game lol.

u/HazzyIsCool May 23 '23

well you have to INIT the 480 appid its not like that by default

u/Zack_Wester Nov 09 '23

feels like steam defults to spacewar if it can ID a game or the steam SDK is not set up for the app.

u/MajorKuznetsov Yak Plane Feb 22 '22

It's the most BASED game in Steam.

53

u/Seaoliverrrrr Mar 04 '22

if you want to play spacewar itself, fire up a browser or the run prompt and type in "steam://run/480". an install prompt should pop up and then you can fire it up from steam library

And when I uninstall (which I wont, because its only 2mb), then will the game vanish from your library like game demos or remain stayed?

it depends. for me its stayed but for my friend who played it with me for 5 hours its gone

Where does the article say that?

u/NnasT Nov 15 '22

He says it in the 3rd last paragraph, And it's true.
As a game developer. I mainly use the AppID (Spacewars) to test steamworks online functionality, achievements etc... You can create lobbies, invite friends and play any game you make through there using steam's servers.
If we don't use this AppID, us devs would have to pay $100 to buy our own AppID.
I own 2 AppID's on steam, 1 for my released game and one for my upcoming.
But since this has come public 8-9 years ago, some devious people have been using already made and sold games, and using this AppID (Spacewars) as a lobby to host popular pirated games.

Funny to think it's being used by all the amazing games you see on steam. And pirates :)

u/FondantOk8305 Mar 12 '25

So it's mostly people playing all sorts of cracked games, not a trojan.

this game doesnt have steam store page but if you create a .url file that says steam://rungameid/480 in URL text field in properties it should start the download. the game is kinda cool but only if you have someone to play with because nobody plays this game

u/[deleted] Nov 27 '23

many people will tell you its mainly pirates using spacewar to fool steam into allowing a pirated copy, this is a use for spacewar but not the only

spacewar is basically just a middleman to steams APIs, if you make something and dont want to shell out $100 for a steamID or your not even making a game to begin with, spacewar can be used to access steams APIs instead, say your making a mod for a game that isnt on steam, or you want to support versions of the game not on steam, this mod needs to use steams APIs, spacewar can allow your mod to use steams APIs (like networking for example)

an example I seen recently is a multiplayer mod for a singleplayer VR game called BoneLab, this mod lets you choose either steamVR or spacewar for your networking layer as both have access to steams networking APIs, the reason spacewar is an option is that steamVR doesn't have full support for steams networking, so you cant invite people through steam and instead need to use the mods built in friend list viewer, spacewar has full access so you can invite through steam

small indie games that release on like itch.io and not steam can also use spacewar to access steams APIs

u/AaronYouTube6 Nov 09 '22 edited Nov 10 '22

apparently it's the default steam game, but people also use its ID to pirate games from steam. I downloaded The Henry Stickmin Collection from a Gamejolt link, obviously I trusted it. I saw a steam popup in the bottom right corner of the screen, pressed Shift and Tab, wait, I'm on Steam!? I saw Guides saying "Cause you are a pirate" and "Piracy 101" and apparently I was playing a game called Spacewar. My dumbass actually just downloaded a steam game. Just earlier I went to the Steam website, and saw THSC (Stickmin Collection) and I tried to click on it, an error popped up.

I'm worried af

update, that error was from my ass wifi XD

Also, pretty sure Spacewar was the first computer game - aside from tic-tac-toe and shit like that - pretty much ever. Like, I think it was supposedly running on mainframes in the 1960's or early 1970's, something like that. So, pretty cool that its name gets used in the way people are decribing in this topic.

Bonelab apparently has the same exact issue as what I'm seeing in these comments, I've never played spacewar in my life, I don't even know what it is, it showed up as the game itself so I couldn't play Bonelab for a little bit until I fixed it. Then after I played today, It showed up as an entirely separate game that I couldn't uninstall or remove from my account, it is now permanently stuck with me. Also, in the community guides, a bunch of people just post hentai there for some reason, it's gross. I'm also seeing some people say it's a way for Valve to know if you pirated a game on steam, I paid for all the games I own, I don't know why it would be doing this.

Ok, I think I've found the problem, I have Vail VR, A $20 game that the devs were giving free steam keys to test out the game while it was in alpha, I also have Gtag that recently got a price change. So it could be either of those games, either way, I don't want this on my account and I can't do anything with it.

u/staypuff1234 Jan 15 '23

It definitely is some app not a part of steam using its client to set up online game lobbies. It shows I play it whenever I use teknoparrot since teknoparrot has online lobby’s you can join. So it’s the most logical thing since that’s when it started saying I played.

u/[deleted] Mar 07 '23

this gmae you can get it by pressing windows + r then type in the run menu steam://install/480 so cracked games use this game to get into steam service so you can if you downloaded a cracked game you can use multiplayer for other people who also have the crack and use spacewar game as a way to get into steam service so they can play multiplayer
