On the Lamb Games has the beta form of their Endless Fantasy Tactics rulebook up on Wargame Vault.
From the website:
Warning: This is a combination of BETA Test and Preorder. Rules are not finalized, art/fluff is missing, and the rulebook will be evolving over the coming months as we work towards finishing things. Thanks to WargameVault’s updating feature you will get every update at no additional cost, and get in at a low price.
