A new minigame feature known as Grub Guardian will be launching in tandem with the new update. Grub Guardian is a tower-defense-style game which, will be available for web browsers and eventually, Android and iOS mobile devices. The game will allow players to link to their Wizard101 accounts, which will enable them to play the game using their in-game pets. As players progress in Grub Guardian, their pets will reap rewards of experience and increased attributes. KingsIsle hopes this will allow players to make progress within the game even if they are away from their computers or simply short on time. For more information about the coming updates, and to join the fun for yourself, head on over to Wizard101's official site.
