I went to visit a Red star and the system indicated that I needed the Sigma Warp drive.

I find this request strange as I already had the Theta upgrade (highest warp drive).

Why would it require me to have a lower end warp drive when I already have the highest upgrade?

Perhaps this is like trying to fly from my house to the corner store in a leer jet versus a bicycle, or are there other factors I'm not considering?

  • Does it really say you need a specific upgrade to reach a certain star? I my personal experience I have only noticed the game saying that I needed to upgrade my Warp drive to get to that star... If I'm not mistaken the highest is Omega for every upgrade and not Theta? Aug 23, 2016 at 13:24

    @Mr.Meeseeks I believe the highest warp is Theta (unless I'm wrong). I had Theta, and it required me to have Sigma installed. Aug 23, 2016 at 13:35
  • Don't know for sure if that is the highest warp since I, myself, haven't discovered that upgrade yet but on some other upgrades I did discover the Omega upgrade. Therefor I thought it could be a game bug that it actually needed the Omega drive but said Sigma drive instead. Aug 23, 2016 at 14:50

If you take a look at Does the different coloured solar system mean anything?, the answer goes into detail that each colored star system requires a specific Warp Reactor to get to.

This is mere speculation, but instead of it being a matter of "perhaps this is like trying to fly from my house to the corner store in a leer jet versus a bicycle", it is more-or-less a preventative for players to farm-hunt for the Warp Reactor Theta and be able to travel through the entire galaxy with a single Warp Reactor upgrade; especially for those who happen to find the Warp Reactor Theta as their first upgrade

  • I did see that answer. I guess it's possible to prevent people from visiting every star without 3 warp drives. However, to me that seems a bit ridiculous. What if I want to put 3 Theta drives to jump farther? I should be allowed to access a nearby star (regardless of color) based on the upgraded warp drive. Perhaps it's because the star emits certain types of energy and only certain warp drives can enter that field? Aug 23, 2016 at 19:57
