Had further thoughts on this with a bit of internet inspiration and people’s comments on here so thanks if you replied.
5 players using a 90x90 Death Star mat with 3x turbo laser turrets.
Round 1-3
1p X Wing (Luke Skywalker)
2p X Wing (Jek Porkins)
3p Y Wing (Dutch Vander)
4p & 5p take turns using the Imperial turbo laser turrets
The Y Wing player positioned to make a trench run at the exhaust port.
The X Wings to cut across their axis and draw their fire attacking the turbo laser turrets.
After 3 rounds the Rebel players notice the guns have stopped and are warned to check their sensors for enemy fighters heading their way.
4p 1 x Tie Fighter (Night Beast) - respawned if destroyed with other pilots.
5p 1 x Tie Advanced (Darth Vader)
Rounds 4-8 are the trench run - if the Y Wing is destroyed then any surviving X Wing can start their run.
If the Death Star exhaust port suffers a critical or two hits in one attack then it starts the chain reaction that will destroy the battle station.
If the Imperials can hold off the Rebels to the end of Round 8 then the Death Star is able to successfully destroy the Rebel base on Yavin.
Hope this sounds feasible!
Might do Aces High type game initially then launch into the Attack on the Death Star scenario so everyone gets used to the ships and everything they have to do on their turn.
Might homebrew the rules on the trench and also the turbo laser turrets.
Amy comments/ideas welcome for the 5p bash for newbies. I want to strip the game a bit and simplify but keep the Star Wars - Original Trilogy theme going.
