I brought IG with DA allies (I know, crazy at 1k points but I just finished painting up my DW and wanted to run them).
For attacker, I brought 3 chimaeras (filled with CCS, vets, all with special weapons) and a hellhound on the IG side. DA contributed a librarian + tac squad in a drop pod w/ locator beacon as well as 5 DW terminators (2 with TH/SS).
On defense, I had a full DA tac squad with plasma gun and plasma cannon as well as the librarian, then 2 chimaeras for CCS and one Vet squad as well as a platoon of IG rocking flamers/autocannons. Also an ADL with autocannon.
First game I had was against the nids. IG shooting didn't do much to them, and they cracked the transports and consumed my precious biomass. The DA did manage to come down, pop the zoanthrope, and then get stuck in assault with gaunts. Game ended as my terminators were merrily slaughtering the gaunts in his backfield, but everyone else was dead at that point. On defense, his flying monstrous creatures just had a field day and I never really accomplished much of anything.
Second game was vs. space sharks and was very competitive to the end as both attacker and defender. A biker chapter master is not something to be trifled with apparently!
Final game was against White Scars bikers (attack list) and then an Iron Hands defense list. Again, very good back and forth. His bikes were in my face turn 1, but I managed to whittle them down with flamers and lots of FRFSRF from my IG. With my attacker list, I managed to chew right through his Iron Hands, getting some very good results with my shooting. Was the first time playing against centurions as well as grav guns, not a fan of grav vs. vehicles!
All in all, very enjoyable! It was amazing to find that you could get 6 games of 40k into ~8 hours of playtime.
