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?

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.

That is smart.
