Alien Onslaught

There is 2 sides, the humans and the aliens. you get 21 playing cards each. you have 4 bases each and a main base. You start a round by taking a random 6 cards from your pile of 21 and then  play a top trumps style game. One person chooses a stat from their card and if its higher than the other persons card then the other person must put that card back away into their pile of 21. Or if the person loses then they do that instead. this goes back and forth until one of you has no cards left. The person who loses has one of their bases taken away and then you go again for another round. You do this over and over until one of you has no bases left and they lose. You take out bases first and then the main base last. 

The bases for aliens are called base ship and main base is the mothership. For the humans the bases are cities and the main base is Earth. 

At the end of each round the losing player can choose a wildcard if they want to. This will be a shuffled pile of four wildcards which contains: take away an emenies card next round (destroy in their colour), take away one of your cards for the start of the next round (destroy in your colour), rebuild one of the enemies bases (rebuild in their colour) and rebuild your base (rebuild in your colour). So choosing is a risk.

If you are playing in teams then same rules apply but you all play 1v1s against a player on the other team at once. So if its a 3v3 there will be 3 1v1s happening at once and at the end of the round  whichever team had the most lost losses loses a base.
