Stellaris has a lot of commands, but if you're a casual player (or lazy) these are pretty much all you need to know.
Stellaris is making enough waves among both the grand strategy and 4X communities to have even casual strategy gamers take notice, and that's really saying something considering the complexity of the game.
Those who haven't tinkered with the game may be unaware of its hefty console command function, which gives players the ability to tinker with most aspects of the game somewhat freely. Visual and gameplay adjustments are both very possible, but delving into the vast majority of what you can do with the console command function is not a task for the unsavvy. It gets complicated, and fast.
While a good portion of the game's commands are either complex or still being figured out by the game's community, there is still a sizable list of gameplay-affecting commands any Stellaris player can easily make use of. These easy-to-use commands function much like cheats and can make your time with the game easier if that's what you're looking for.
To access the command console, press the tilda (~) key while in a campaign.
The commands below are the game's most simple and primarily function as cheats. Commands with their examples listed as "N/A" in the "Example" column are simply the command itself with no other inputs but the trusty Enter key.
