From the box (in portuguese):
"Você terá apoio do seu exército para enfrentar os adversários nesta disputa. Vence quem for o melhor.
Uma grande parte do planeta Terra esteve imersa por milhares de anos. Este novo mundo emergiu e se tornou alvo de muitas nações que irão batalhar ardorosamente para conquistá-lo"
In English:
"A big part of Earth planet was emmersed for thousand years. This new continent has emerged and became target of too many nations, that will fight to conquest it".
In "Batalha Territorial", you command a civilization that must conquest different types of territory (water, ore, earth and forest), with pawn placement (soldiers).
Lucky factor is high, due to dice and card draw. The cards are the essence of game. For the player, the only decision made is where to put the pawns (soldiers), and depends on the card taken.
The dice rolling only happens in the end of each round (the game has only 2 rounds). The result is summed up to the player's total points.
