If viruses and Napoleon have taught us anything, it's that the deadliest of threats can often be the tiniest.

The Andromeda Strain Challenge was a special challenge for the game Nano War that was released on July 20th, 2008 and lasted until July 27th, 2008. Unlike other challenges, it was released on a Monday, the same date of Nano War's two badges, the Tiny Victory Badge and the Microscopic Mayhem Badge. To complete it, the player had to reach level 9. Completing the challenge would give the player the Replay 1 version of the Andromeda card.


This challenge was the first in the series of "Monday" challenges. Afterwords, challenges were released on Mondays and Thursdays, instead of just on Thursdays.
