Based upon the standard Risk board, this map adds control of the oceans to the battle.
Capitals Scenario!
Star territories are 'Capital Cities'.
Continents
Continents are worth the same as the standard board.
Capitals (marked with a star) are worth +2 all by themselves. If you take any capitals and then lose all your capitals, you will be eliminated, and 1/3 of any remaining troops will be given to your eliminator. Capitals can attack any terrtitory in their continent. Capitals defend and attack at +1, and this bonus is accumulative with the harbor defensive bonus, so a capital being attack from the sea, defends at +2.
Harbors (marked with an anchor are also worth +1 all by themselves. All ocean territories are worth +1 (+2 total for harbors) if you also control every adjacent ocean.
Attacks between land and sea are only allowed when there is a harbor in the ocean territory. there is a +1 to defense (both ways). Harbors are indicated by an anchor icon.
Islands
Please note that unlike the regular risk map you cannot directly attack islands from the main continent. You MUST go through the ocean to complete some continents, or use the border from a capital.
Starting Scenario
Player territories - 4 units
Capitals - 2 units
Anchor territories within a land continent - 3 units.
Anchor territories between land continents - 4 units.
Red Sea (i.e. O33) is a special case, and starts with 3 units.
Bering Sea (i.e. O1 & O5) is a special case and starts with 6 units across two harbors.
Math
For 3v2:
+1 to defense - average loses of 1.25 attackers per defender
no bonus - average loses of .85 attackers per defender
