None of us had played Kill Team before, and it's kind of a toss up whether we will again.
In addition to my DA/SoB army, Erock played Chaos (I didn't get a roster from him), Ammon played 10 Necron Deathmarks that were 100% identical (and I believe 100% stock), and Aaron played Grey Knights.
At the end, it came down to three of his Berserkers and his Sergeant against my Space Marines, where he whittled me down.
In the second set, Ammon and Erock faced off (I honestly don't know who won, there), and I faced Aaron. I dropped my Repentia for another Space Marine (I know I had a backup plan, but I nixed that).
We both started by sneaking around buildings -- I got my Space Marines into the same high ground Ammon used the round before, and covered the middle ground with my Sisters and Terminator.
My Terminator took out his all but one of his Terminators, my sisters took out most of his Grey Knights, his Terminator took out my Seraphim while his remaining Knight wiped out all but one of my Space Marines, so my Terminator bashed in his Terminator with a Thunderhammer, and it all came down to one of my Marines, my Retributor, and my Termie bashing on his remaining Knight in assault. It was probably Turn 9 when the dice gods gave me that 1 on his save I was waiting for.
Erock and Ammon teamed up with Chaos / Necrons where Aaron and I teamed up across the table with Grey Knights and Dark Angels -- I took the Dark Vengeance set, minus the Librarian plus Belial to fit the FoC.
Turn 1 was where it started going downhill for our side -- Erock and Ammon killed off all but one of my bikes, I don't believe we killed a single thing of theirs.
So, for the next two turns, our 11 Terminators took EVERYTHING they had. Monolith, Deathmarks, the Land Raider...
After they killed all 6 of mine and 2 of Aarons, we called it a night (we'd been playing for 8 hours, and it was 11:30 PM).
The two things I learned from this game are: Sisters with flamers are AWESOME, and I need to be more efficient with my Fast Attack.
