We have word that the mysterious Myth: The Total Codex Product will indeed contain Chimera. Supposedly (ie. judging from the pics on the boxes), the Codex will contain these things:
Myth: The Fallen Lords
Myth II: Soulblighter
Myth II: Chimera
Myth:TFL Strategy Guide
Myth II Strategy Guide
We should have more info about this coming soon. Stay tooned!
