This is going to be a short post today. A fellow legionnaire and I have started a story driven campaign. My Tyranids are invading a planet protected by the Sisters of Battle, the Carcharodons, and some tasty Guard.
The rules are pretty simple, the Nids, being an invasion Hive Fleet, have an unlimited supply of troops. My opponent has very limited troops. The allies that get to the planet before the invasion are all he has. As they die off, they cannot be replaced.
The first mission, which was played today, only involved the Sisters. The story will be told later.
