SCORE is just a codename for the first iteration, or TIER 0, of the mini-game. SCORE allows you to stake your ships in a game loop that rewards you with ATLAS for your active participation in fleet enlistment and maintenance.
On December 16, 2021 the Star Atlas team released the first module for the mini-game, titled SCORE — Tier 0. SCORE is an acronym for Ship Commissions on Remote Expeditions. This module enables you — for the first time ever! — to stake your ships in a game loop that rewards you with ATLAS for your active participation in fleet enlistment and maintenace.
In order to partake in the action, you need to own at least one ship.
Despite the peace treaty that was signed between the factions nearly 100 years ago, conflict between the three factions has started to escalate again. To better protect borders and to try to get an edge in this conflict, each faction is feverishly trying to bolster its forces. To that end, they are asking their people — meaning you — to enlist as many ships as they can spare. To incentivize people to join their cause, they offer them a rich reward (ATLAS) in return.
It’s important to note that it does not matter what roles your ships can (normally) fulfill, nor whether they are attuned to combat. As with most conflicts, besides combat-heavy ships, there is a need for support vessels as well.
Bottom line: All ships can be used in SCORE.
