One of my first armies back when I started playing miniatures games was a Tyranid force for 40k. They were still relatively new back in 2nd edition. They were just so cool and alien (and I’d not even seen Alien at the time). Well, for those that might want to get into the faction, there’s a new Tyranid Codex available to pre-order over on the Games Workshop site. They’ve also got bunches of other things, much of which would fit in today’s Terrain Corner. Also, bunches of paint sets.
From the website:
The Tyranids are unlike any other race to be encountered by Humanity. They are the ultimate predators; to them all living things, from the lowliest insect to the most advanced civilisation, are mere prey. Only now are the inhabitants of the galaxy realising the scale of the threat – unless the Tyranids can be stopped, it will mean nothing less than the extinction of all.
Codex: Tyranids contains a wealth of background and rules – the definitive book for Tyranids collectors.
