There's a new Tyranid codex coming soon for 40k. And along with updated versions of all the regular troops you know, there's new ones as well. In this preview, we get a look at the Parasite of Mortrex. You're gonna need a bigger can of RAID.
From the article:
This huge flying gribbly – first encountered on the planet of Mortrex – was originally mentioned in the 5th edition Tyranid codex, and Crusade rules have allowed Tyranid characters to mimic its horrifying implant attack… but nothing compares to the real deal. With its new plastic model, this classic critter is lunging out of the lore and onto the tabletop for the first time ever.
