ANDROMEDA You have the Power of Potency Each time you lose a colony (foreign or home), use this power to draw an additional alien power (if the alien has Game Setup text or is not allowed in the current game, discard it and draw again). If, after you have added a power, you gain a foreign colony, you must discard one of your additional powers.
The Warp Alien Power database has over 2000 entries you can look through, including every offically printed alien (search by author, origin, expansion, variant, and more). Just click on "Homebrew of the Day" to access the Amazing Alien Database. If you play Cosmic Encounter long enough, you eventually find yourself in The Warp.
Normally, you wouldn't find this many zombies in the warp...
