From Mars they came

In From Mars They Came, 4 players divided into 2 teams, fight against each other to gain control of the White House. Combat works similarly to Rock-Paper-Scissors, but is played out with units on a board and may be affected by different Abilities and Events in the form of cards. The Human factions" objective is to defend the White House and a total of 4 defensive positions to collect points, 25 to be exact. The Martian factions" objective is to reach the White House and stay there for 1 round. Be careful not to trust your teammate too much though. In the end, only one nation can be fit to rule Earth from the White House.
