PoxNora: Battlefield of the Immortals is a multiplayer online game that combines a collectible card game with a turn-based strategy game. PoxNora is launched via Java Web Start through a browser and can be played on Microsoft Windows, Mac OS X, and Linux. The game is free to play with "Sample Battlegroups" and players can purchase additional game pieces, called "runes", and build their own strategies. The game included nearly 250 runes in its premiere set and first expansion set, and a second expansion released on January 2, 2007 added close to 100 additional runes.

Players build decks, called "BattleGroups", on PoxNora's website. A Battlegroup consists of twenty runes in any combination of spells, relics, equipment and champions. The game is launched via Java Web Start and players enter a lobby where they can chat or enter games. Games consist of two players, though matches against AI "bots" are coming soon[1].

Each player's Battlegroup is shuffled (like a deck of cards) and players reveal two runes per turn (except the first turn, when three are revealed and the second player's first turn, inwhich four runes are revealed). The game is played on one of 8 different square, "tiled" maps with various obstacles, fonts, and a Shrine representing each player. To win, you need to be the first to destroy your opponent's Shrine.

Players accumulate Nora (magical energy) each turn and can use it to cast spells, deploy champions, place relics, or use equipment. When a champion rune is played, it appears on the game map and can be moved around, just like any other tactical roleplaying game. Champion movement is limited by their Action Points (AP), which they regenerate at the start of your turn. Champions gain Champion Points (CP) as they participate in battles. You can spend CP to improve or add to your champion's abilities. Tokens can be used to reset a champoin's spent CP, as well as to provide bonus CP.

The game is free for trial play, but to be able to upgrade runes, create your own custom BattleGroups, or to trade for other runes it is necessary to purchase your own runes. $3 US buys a pack of 10 runes. $25 US buys a pack of 100 runes. Many players also purchase a premium subscription, which costs $5 US per month. The premium subscription gives access to a few special runes that cannot be found in normal packs.

You can even trade your runes with other players from around the world to get better runes or to make a better deck. There are several "rune shops" in the Trader forum that can give players a good idea of what their runes are worth. For an automated approximation of rune values, see the fan site PoxShop. It is important to do some research before you trade, as there can be some dishonest traders.
