Achievements in Steam!

Dear friends,
We’ve started designing Steam achievements for the game (you can see some examples above). The process has already begun, but you can still participate in it.
So, who of our supporters wants to help make an achievement? Is there anyone out there?
Well, the terms are simple:
You simply need to come up with a really cool/interesting/nontrivial achievement that’s appropriate for the game and describe the conditions the player must meet to earn it in the comments beneath this post. We’ll consider commented suggestions from across all platforms where a post like this is made.
We look forward to seeing what you devise!
