If you don't know what Fate is, here's the link the downloads.
This game will take place in the same Brikverse as all the Brikwars games, Warhead is splintered, the Immortal War is still a thing that is happening (Including Zombie Zulu Dawn), and so on; but using your choice of Fate Core or Fate Accelerated.
The plot? You and each of your respective squads (NPC's the you write-up, but I control) have each be tasked w/ the exploration and recon of a newly discovered space-faring nation (the fact they've achieved Vast empire status before be noticed is still being examined be the higher ups). This region of space has come to your respective factions' attentions because there has been a dangerously high level of peace and is getting more peaceful by the second. Your mission: confront this menaces to Minifig society and let them know of their wrong doing by mitigating conflict. Ironically, your orders also state that violence is to be reserved as a last resort, or until the mission is a success, whichever comes first.
