Codex: Tau Empire has brought the Mech-loving blue skins into line with 7th edition. Not a lot of changes to the base units, but the addition of Warlord traits, Formations, and continuing the datasheet style make this a essential book for Tau players. Not much artwork, but lots of very good quality photos of models.
Some of the changes were expected, Hammerheads and Sky Rays can now be fielded in squadrons of 1-3 vehicles, and Piranhas expanded to max size of 5. The surprises for me where that Riptides are now 1-3, and VX-8 Crisis squads are 1-9! This will be fun. Of course the newly released units are in the Codex: Breacher Teams (Fire Warriors with Pulse Shotguns) The Commander in fancy Enforcer or Coldstar battlesuit, the Ghostkeel, (big stealth suits), and the very big Stormsurge artillery suit. And new Drones. Lots of new Drones. The Tau now have more drones than the NSA.
I plan on bringing the Tau to the table this weekend to see what tweaks were made to all the support systems and such, there will a battle report next week.
Overall, I am well pleased with all the books and look forward to dealing Mecha-suited death.
For the Greater Good
