Destroy All Humans!

At the mothership, use RB or LB to switch to "archives" and select "Furongami" to unlock this achievement.

Here is my 100% Achievement guide and full walkthrough so you don't miss a thing.

So we can unlock this at the very beginning of the game.
When we load up, you see alien dude meister (forgot his name haha) as a hologram sitting in a chair.
This indicates your on the mothership.
From here, simply press to go into the archives, scroll down and select "Furonigami" and the achievement should unlock straight away.


Go to 2:10 in my part 1 video to see where and how to unlock this

Hope this helps!
