The Galaxy Map
In the image below, you'll see the Solar System Map, which features a new bar along the top. More importantly, when you click on a planet you can see how many Arenas it has, and then build your own stuff (More on this another time though!!)
But once you have enough cash, and your fighters are dominating the Pit-Fighting-League - you'll want to move on. Below, you'll see the second tier of the Galaxy Map (art is WIP) - displaying the different Stars, and the different Pit-Fighting-Leagues you can join.
The types of stars as well as the number, population and types of planets in each Pit-Fighting-League are all randomly generated at the start of each new game. However they have environments based on the distance from the star itself. Molten planets will be closer to the star, while water heavy planets are further away.
You'll not only face tougher opponents in the higher-tier Pit-Fighting-Leagues, but you also won't have a clear idea how strong they are. At least until you spy on them! (For a small fee!)
Once you've fought someone you'll know all about them though, right down to the contents of their organ cavities (gross). So do you take the risk of fighting the unknown, potentially losing a Slave? Or spend some of your precious Credits on gaining Intel? Next time you'll know all about them - maybe it's worth it?
The Pit-Fighting-Leagues and their broader elements will be a key part of the meta-game. So there will be a more in-depth article about that another time!
After each fight you'll be able to see a breakdown of how your fighter fared in battle. More importantly - you can see what sort of horrifying injuries were inflicted!
There's nothing quite like severing the hemispheres of your opponents brain - even if you lose!
The Drug Trade
Finally, a little bit on markets.
Refined Human Goo is not the only drug available in the game - you can also administer far more mundane drugs, like Steroids and Opiates to your Slaves. They're also a lot cheaper! However, the markets will vary from Planet to Planet, and from Cycle to Cycle (an in-game week). A vigilant tycoon could turn a tidy profit moving drugs between worlds, then selling to those in need!
