In Space engineers, there are factions, blocks, thrusters, weapons, and all sort of stuff to survive in the world of space and planets.There are too game modes creative and survival. In creative, you can build things with no resources and you cant die from any natural or unnatural causes ( unless you set a border for the world then you can die ).In survival, you need resources to thrive and survive the harsh conditions and build ships to fly around or colonise planets with different conditions to survive.

Factions
In space engineers, there are factions that you can create or join (if someone already made one) so you can survive with other people online, and make it easier to create.

Space ships and stations
In this game, there are ships that you can create with multiple types of thrusters to make your ships move around and attack other factions. You could also use these ships in survival to industrialise quicker or gain resources for your colonisation purposes. You could also make space stations to store your ships in a place where you can adjust or repair them. There are 3 types of thrusters Ion thrusters, Hydrogen thrusters, and Atmospheric thrusters. Atmospheric thrusters can only work in atmosphere, Ion thrusters can only work in space, but Hydrogen thrusters can work in both atmosphere and space. There is also something called a conveyer which if used correctly it can transport recources to different areas of your space station or ship.                                                                                                                                                                                                                                                                                       Weapons and tools                                                                                                                  Weapons in space engineers are quite simple, their are 2 types of turrets and 3 types of small guns and also 1 hand gun.The 2 types of turrets are gatling turrets and missile turrets.
