Since Star Wars: the Old Republic is quite a different game, you need to know it before playing. For those players who have not played it before, it is not a easy task to finish his first space mission. Don’t feel anxious, if you know several things, it will be easier to finish it and make the SWTOR Credits.
In order to get your own Starship, you just have to follow the story line quests. Around level 17, you will get the quest that will lead to your own ship. You can get it as soon as level 14 if you focus on the main storyline, but it is unwise. The first mission you will have to do is going to be an escort mission. This is for both factions and the missions are almost identical.
First you have to understand how space works in SWTOR. You won't be able to control the main trajectory of your ship. It has a set course in the instance which you cannot deviate from. You will only be able to control your target and make small movements across your screen to avoid objects and enemy fire. You saw right, you have to avoid objects. If you hit an asteroid, another ship or other debris of larger size, you will get damaged.
As soon as you begin the mission, you will see the ship you have to escort in front of you. Even though there will be a lot of lasers flying around and much larger ships firing at you and the escort, you need to remain calm. Focus on killing the Interceptors that pass you by. Those will do the most damage to the escort ship and to you when they turn around. So kill them before they have a chance to do this.
When there aren't any Interceptors around, fire at the turrets of the enemy cruisers. You don't have to hit them much, so fire a few shots at one and move quickly to another. It will take a while for your shots to reach them so don't target one until it is destroyed. Only use your missiles on generators and such. To fire them, put your cross-hair over the target and right-click. The missiles are Fire and Forget, which means that they will go to the target themselves so you don't have to keep your cross-hair on it.
Kill as many turrets as you can and you will also do bonus objectives in the mission. If done right, your escort target should have 50% HP by the time it reaches the destination.
When you upgrade your ship, focus on defensive capabilities as your fire power will be enough. In order to regenerate your shields during combat, you will have to stop firing. This will help you survive in any mission pretty easy. Still, in order to succeed in the other missions, which are a bit more complex, you might need a SWTOR Space guide.
To make sure you have all the data you need to complete every mission, no matter how hard it is, you need to get enough SWTOR Credits.
