Which is the mission 'Out of bullets'?

I would like to get the achievement Out of Bullets but I don't have the English version of the game. Can you please tell which is the number of mission called 'Out of Bullets'? Or post me a screenshot of that scenario?

Okay, so this achievement is a little missleading. It's not a mission or campaign pack that's called "Out of Bullets"; instead, it refers to a specific challenge mode available to some story missions (5 in total)

It's not the name of an actual mission. It's a mode for the normal original levels. See:

Edit: I took screenshots of the first mission that you can play in 'Out of Bullets' mode (which was added in a recent update).

Search for the Out Of Bullets game mode on five of the original levels. Select campaign "The Awakening" and mission "Ancient Research".
