The Ember Conflict is a real-time tactical game for iPad and Android tablets. It is currently in public beta. It offers deep tactical and strategic gameplay with highly customizable armies. And since this is the TEC wiki which is curated by the community, you'll forgive us if we say it's the best stinkin' thing you could ever hope to put on your tablet. The game is formatted with an eye towards esports and, although free-to-play, is not pay-to-win or exploitative of the player with paywalls, timers, etc.
The universe within which the game takes place is full of rich lore and history, although not all of it has been revealed.
