Here's a quirky team deathmatch variant I just cooked up.
EDIT: I wrote up the rules in more detail. Here they are.
Each player brings one ship, built however they choose.
This ship MUST be a unique pilot or feature at least one unique upgrade card. In addition to their tokens and that stuff, each player must bring one debris field of their choice.
You may not exceed 33 points when building your ship.
Come up with a few "fallback" ships as uniques will be recognized across all players. If two players bring the same unique pilot or upgrade, the player who spent fewer points on their ship gets to use it. The other player must then resort to a fallback ship/build. If points are tied, choose randomly if players cannot agree on who get's to use the ship/build.
Once everyone has their ship ready, players are divided into two teams as evenly as possible.
Initiative among players will be determined according to points spent, and then randomly in the case of ties. Initiative always goes to the team with the player who is highest on the initiative list.
Teams take turns deciding on where to place 4 asteroids on the field according to normal setup rules.
Then each team sets up their ships on opposite edges of the field.
When you are defeated, place your debris field token on the field where your ship was when it was destroyed.
During the game each ship has two special actions it may perform instead of a regular action. These actions are not considered to be in your action bar nor on an upgrade card.
Defect: ACTION: You switch to the other team.
Recruit: ACTION: Receive one stress token to force an enemy ship within range 1-3 to change to the other team.
If all ships are on the same team, there are no teams and it is a free for all.
Each ship will be assigned a double sided token to show which team it is currently on. Flip this over whenever you switch teams.
Whenever you defeat a ship, you gain points equal to the point cost of that ship+upgrades.
At the end of the game the player with the most points wins.
Last ship alive receives 20 bonus points.
2nd to last ship: 15
3rd: 10
4th: 5
