Tyrant is a free to play, browser based Collectible Card Game (CCG) based on the War Metal game and is set dozens of years in the future. Gather your Imperial forces to defend against a massive onslaught from the brutal Raiders, vile Bloodthirsty beasts, and the mysterious Xenos.

Massively multiplayer online game play is provided through a Web browser using the Flash platform and the battles within the game may be set to automatic or manual. Each mission shuffles the player's selected deck which includes a commander and up to ten other cards. The player is then presented with three cards from their deck to choose from for the first turn. Turns alternate between opponents until either commander's health reaches zero (the other side wins), or the health of both commanders is above zero by the end of turn fifty (draw in tournament battles, the attacker loses otherwise). Strategy is formed by taking advantage of card skills and choosing when to play which card from the player's hand.

The new player is presented with a choice between two commanders and a tutorial which can be skipped. The tutorial will walk the player through the first two missions and introduce the player to the store. card packs may be purchased in the store to supplement the cards awarded for mission victories. New decks, card packs, and rewards are unlocked for completing levels,achievements, and gaining reputation. As the player progresses in level, opening new missions and unlocking new features, a tutorial message may introduce the player to various game features.

The player can track their progress towards the next level, as well as the amount of energy, stamina, gold, and war bonds available via the status bar in the game interface. Buttons include those which allow for navigating the various panels within the game interface, toggling Automatic Battle Mode, as well as turning sound effects and background music on or off.
