Retribution is a combat strategy game in which each player is attempting to completely clear the battlefield of the other players units. (Exception: if played with the unit, King, the game ends when he is killed)
Setup
Players will collectively or randomly choose 10 units to play with this game. Each player has the same 10 units in thier army but with a dividing wall between them they place their units onto the board in any fashion that they choose. Then the dividing wall is taken down.
Game Play
Players then take turns activating two units each turn trying to decimate the others army. Each unit is unique in its abilities, attack, movement, and health. Although each player starts with the same army, every time one of your units is killed you get to upgrade one of your living units to its advanced version. This freedom to advance the units as you choose along with the 18+ unique units that the players have to choose from to play with gives the game incredible replay value!
