Thanks man, glad you enjoyed! Went full FedSuns on these guys.
Skills were all defaulted to 4 for both sides to make it easy.
Yes, the infantry swarmed same turn, which is definitely not ok via the rules (looked it up after). Personally, I'm pushing my opponent to allow a house rule where infantry deploying from a VTOL via zip lines or jump jets can attempt the anti-mech attack the same turn with a penalty, as it doesn't make sense to land and then climb the mech again. But I love infantry, so I want them to be effective. :)
I bought what I could with the BV available, sadly, the same amount as the mech player. I'm actually pretty content with the damage I did, considering my pretty major mistakes. If one or two shots had happened differently, the Battlemaster would have gone down I think, and several mechs lost arms and took internal damage. It encouraged me to try again if nothing else!
The Savannah Masters did indeed go for rear shots almost every time, however there was a moment where they didn't quite reach the rear of the mech, and ended up taking frontal shots against the most damaged one. It did feel like too small a force, honestly, but it was our first time doing a strictly BV based battle.
I'm really only into the SW period, so I'm not worried about advanced tech.
