Popcap has announced the Trials of Gnomus update for Plants vs. Zombies: Garden Warfare 2 that adds game modes, a new loot system, and balancing changes. Trials of Gnomus is available today, September 8.

“Trials of Gnomus introduces the Mystery Portal, a magical gateway built by gnomes to test the skills of the plants and zombies,” said Marcel Kuhn, producer of Garden Warfare 2. “Players can travel through the Mystery Portal to play three all-new limited-time game modes and earn Rainbow Stars to unlock Rainbow Chests and the Gnome Underworld.”

Additional content added to Plants vs. Zombies: Garden Warfare 2 includes new quests for the Quest Board, a new map, and Rux the Deal Breaker, a roaming sewer merchant that sells rare items.

Listed below are game modes available for a limited time:

  • Cats vs. Dinos – face off in a Jurassic battle of felines versus dinosaurs in this fast, competitive game mode fought in a new extra-large Gnomiverse multiplayer map.
  • Boss Hunt – team up with friends and take on the ultimate PvZ challenge as you battle epic bosses. Battle on higher difficulties to earn even bigger rewards.
  • Super Mix Mode – a new, crazier mix of Crazy Settings featuring different combinations of characters squaring off against each other.

The update also includes a lengthy list of fixes and balancing changes that can be viewed in the official patch notes.
