Universe Sandbox 2

Universe Sandbox, a very large-scale “universe” simulator, puts everything that has been discovered about the universe into our hands. We can place all the objects discovered in the universe as we want, within the framework of the laws of physics, and create new solar systems and galaxies. By manipulating the characteristics of planets, we can create new planets with life. In other words, what you can do with Universe Sandbox is actually unlimited within the laws of physics.

Kerbal Space Program

One of the first steps to doing something in space is to naturally go into space. Kerbal Space Program starts you exactly from this point. In this game where you try to build your rockets and go to the planet you want with the method of endless trial and error, you help the not very cute creatures called Kerbal to conquer the universe. With Kerbal Space Program, you can discover the laws of physics and experience the pleasure of building a successful spacecraft.



Observation, an Indie game released in 2019, tackles a very interesting and possible topic. Observation, which is also called an interactive science fiction and thriller movie, deals with the drifting of a space station of the same name from Earth’s orbit to a point near Saturn.

At the same time, the station’s artificial intelligence, SAM, is behaving strangely, and things are starting to get pretty bad for Dr. Emma Fisher, who is on the station. Another interesting aspect of the game is that unlike the traditional approach, you play the artificial intelligence S.A.M. instead of Dr. Emma.

Outer Wilds

Outer Wilds is a role-playing game with a primary point of view, but unlike most games of this genre, Outer Wilds travels interesting galaxies and meets strange alien races. The point where the game gets interesting is that the character we play is stuck in a 20-minute time loop. Every 20-minute period we study planets in this strange solar system and try to learn more about the mysterious alien race, the Nomai.

STAR WARS™ – Knights of the Old Republic™

When it comes to aliens, we can’t get away from the horror genre. Alien: Isolation, one of the popular horror games of recent years, continues the legend of the cult film series by giving it its due.

The Callisto Protocol

Another survival-horror game with a space theme that has been released recently is The Callisto Protocol. The game, which we can define as the spiritual continuation of the Dead Space series, warns us, not for sensitive hearts.


The game, produced by Arkane Studios, which we know with successful productions such as the Dishonored series and Deathloop, takes us to the moon colony. But as you know, in a game like this, it doesn’t happen if things don’t go wrong! While running away to avoid being hunted, the game that we try to solve this problem also draws attention with its different mechanics.
