I am so happy about the new Tyranid codex. They are my favorite army to play against BAR NONE. I'm really, really, really hoping I see more Tyranid players in my area. You get to kill lots of stuff, fight in melee, have great shoot outs (especially with stuff like the Exocrine), try out out maneuever Lictors and Genestealers, and have epic duels with with their character bugs like the Tyrants, Broodlords etc.
I'm so stoked they look so strong.
