Here is the video release for the new Tyranids today. The video gives you close up views that are otherwords hard to get. These are excellent models, and I am considering restarting a tyranid army from this release.

Many of the new models are also plastic kits, which means there are loads of different options included in the box, from guns and claws to heads and tails. You get to see a lot of the parts in these videos, a useful resource if you want to find out how to equip your new units. Put it this way, the Hive Tyrant can now be geared up for total war with wings, a Heavy Venom Cannon, Bone Sword, Lash Whip... well, everything really. You can even build the Swarmlord from the kit. Check out the videos and see for yourself.
