Update: Kleos has launched on Kickstarter and the campaign will run for 23 days. At the moment there is only one pledge tier open, that gets you a copy of the game ('Choose your own epic hero' option closed).
The FAQ section in the campaign says that the solo scenarios will become available online, and all you need to play them will be inside the box.
Kleos is a 1-5 player dice rolling and hand management game about Olympian gods competing for fame and glory (what 'kleos' means in ancient Greek). It is launching sometime later today.
In Kleos, you play as either Athena, Ares, Artemis, Hermes or Dionysus. Your goal is to become the patron god of the city of Kleos, and you will achieve this if your army defeats the forces of your opponent(s). Each of the gods plays differently: they have their own champion, and their own deck of cards. At the start of the game, you get a hand consisting of two cards specific to your god, four cards from the Fates main deck, and one card from the god's Divine deck. Then, in the Deployment phase, you choose minions from your hand and put them into play.
In the Play phase, you play cards from your hand, and in the Action phase your minions on the board can take 2 actions (move, attack, or recruit an epic minion from the Greek Isles). At the end of the round, you draw back up to your hand size, tally up the score from the board, and continue with the next round. At the end of the fifth round, the game is over, and the player with the most Glory wins.
Kleos comes with solo scenarios which haven't been revealed yet. You may check the Kickstarter preview.
