Cluster Bombs and Y 666. Yes, I know these are Cargo. Yesterday we played one Scenario depicting a Rebel strike force against a Scum weapons dealer with elite bodyguards. Prior to set up the "DM" adviced Rebel players (my team) that the Y 666 was highly modified with hidden upgrades not on the table. One YT 1300 and one YT 2400 with simple boarding rules to storm the cargo vessel... if affected by Ions.
So 3 B wings close in to ion that big thing. R3 firing and only one Ion Token. Next turn R1... Old Teroch finish B Wing leader ( RIP Keyan). After much shooting time for PS 2 Blues to attack. Hit. Second Ion token on the YV. And Cluster Bombs.
2 Reds to all ships within R1. Minor damage against the Blues. Porkins kaboooom. He didn't saw it. Hidden Cluster Bombs to protect that valuable cargo. Shock and Surprise. Next turn I touched that ship with my YT 1300 Chewee...but also over a little asteroid. So no Boarding Action.
90 min later Sabine Tie detonated the EMP Device and my pal boarded the YV and captured it, after defeating the mercs defending the cargo.
I was surprised by this trick. Many laughts. I own Imperial Assault but no time... so many games. Perhaps one day we will try boarding actions with IA.
