As a player, you will be exploring Mars as a colonist. We are here with the "You ask, we answer" rubric to give you more insight about colonists.
How many colonists can a player have?
Each player (whether a landowner or not) will have access to 1 colonist for free. If they want more, they can buy additional colonists for themselves. These are separate from the land NFTs. It is entirely possible to play Mars4 without owning any lands (by playing on other people’s lands) and equally possible to own many lands and choose not to play (by assigning a manager to handle the in-game land on your behalf).
