Quarriors! is adding in a new expansion pack called "Quarmageddon" to the game, and to mark the release of this expansion the app is going free for a limited time. The expansion pack costs $1.99, so this means the game and new expansion are available for a total of $1.99 for a short while.
Quarrors! is the mobile version of the board-based dice-building game of the same name. It is a faithful rendition, as our review late last year noted.
The game is available on the App Sore; it returns to regular price ($3.99) next week on March 20.
