Much different and stronger than a Streuner, a Boss Streuner is an alien that is a good reward source when starting off the game.
The Boss Streuner is the Boss version of the normal Streuner. It is four times stronger than the normal version and is looks different visually. It is easy to kill for most players but if you currently have a Phoenix ship, you should make sure you are prepared and ready to take one of these on. Boss Streuners are a good source of rewards and cargo drop for new players in the Lower Maps.
