Hello, I'm new to Warhammer 40K and any kind of Wargames, and I have decided to play as the Tyranids. So far I have a small little army I've tried putting together. This week I will be playing in a tournament at a local store where you can only start off with a max amount of 200 pts. Every two weeks another 200 pts is added on to an army. So far I have about 12 Termagants, about 12 Hormagaunts, and 3 Warriors. An HQ doesn't have to come into play until the 5th week of the tournaments so I haven't gotten one just yet. Any ideas for improvements?
