I recently downloaded Chronicles of Blood which is a free PDF from Crystal Star Games via RPG Drivethru or Wargames Vault.
It is a Fantasy game and the PDF contains 14 pages. The rules are nice and simple and the mechanics use different types of polyhedral dice for their Fighting, Damage and Morale stats.
The stats are there for the basic types of figures. the intention is to bring out premium content for $1 each (62 pence).
The Company also has a solo RPG Adventure too called Chronicle of Arax which is also recommended.
