The press also spoke at length of this new expansion.
PC Gamer felt it's a really good addition to the game, while Gamewatcher highly recommends it to any Gladius fan. Explorminate awarded Gladius the title of 4X Game of the Year and also reviewed the Tyranids' unique mechanics in this video.
If you'd rather listen to a podcast, the guys at Three Moves Ahead ran an episode about the Tyranids just yesterday. If you belong to the francophone audience you might want to read Wargamer France's AAR while if you are an Italian native speaker don't miss the review from Tom's Hardware.
These are just a few of the magazines and online sites which reviewed this DLC. Which one did you like most?
