Yggdrasil

Yggdrasil is a co-operative game in which players are different gods of the Norse mythology: Odin, Thor, Tyr, Frey, Heimdall and Frejya. Monsters, the wolf Fenrir, the huge serpent Jormungand, the Fire Giant Surt, the Goddess of the Dead Hel, the traitor Loki and the cosmic dragon Nidhogg are moving forward in Asgard inescapably and announce the impending coming of chaos and destruction on the world tree Yggdrasil. Together the players have to resist to the impending coming of the Evil forces in Asgard, the gods' world.

Game flow
During his turn, the active player first draws an Enemy card, corresponding to one of the six Evil creatures. The corresponding counter is moved one space forward in Asgard and the associated effect applies. Then the active player performs three different actions among the nine at his disposal in order to resist to the advance:

Ask for the Elves' help
Get a Weapon from the Dwarves
Send the Valkyries looking for Vikings' souls on the mankind world Midgard
Fight the Giants and try to gather the parts of a magic rune
Negotiate with the Vanir
Get rid of the Fire Giants who invade Midgard
Get the Vikings back from Hel's world
Exchange forces with another god
Fight against the Enemies in Asgard

Each player, depending on the god he plays, has a specific power that allows him to perform some actions better. All of these actions have to be used in the right moment or the victory will be unreachable. The players will need cleverness, calm and team spirit to challenge the game.
