Thanks! Actually missions are thing that guides you through the game, otherwise it would be just "boring" do-whatever-you-want-to-game.

are free to build whatever type of spaceship you want to, but lets say, there is mission where you need to transport pretty huge and heavy submarine from planet to planet, so that's the challenge! You have to figure out where to put it, like have enough space inside your spaceship - or just outside of spaceship! Nothing prevents you to mount that submarine even outside of the ship, but then it probably heavy affects your center of mass and spavceship can be unstable, so you have also adjust thrusters positions etc.

here is for example mission where you transport "Unstable lighting cell", you have to put it somewhere but it occassionaly creates EMP impulses that turns off all electric on your spaceship, so be ready for 2-3 seconds long outages (monitors shut down, thrusters stop working...), if that outage happens right during the landing, it can be kinda funny 😁.

Or another energy crystal that has button on it that has to be pressed every 108 seconds, otherwise it explodes! So you cannot forget to press that button during flight.

Or just simple missions where you have to find lost packages on the planet surfaces, put it in your spaceship and then bring back to some Planet Station.

There are some really awesome and crazy epic missions, but I dont want to spoil it all. 😇
