1. an alien civilization discovers the colonies and it culminates in a war. Halo

2. Based on the player actions either the aliens forms an alliance with us or we manage to fight back, making them to retreat or they destroy the colonies and invades the Earth. What happened to the alliance?

3. Playing as an alien fighting humans would be awesome since the player can get both sides of the story and using alien guns would be cool. Sounds too complicated for a game, maybe a series but the plot sounds nothing like COD.
