Apocalypse Night

Unfortunately the game does not show you how to this can be done in the tutorial.. and since this game does not have key settings, there is no way for you to know which button to use to call the Air Strike, unless you press all buttons until you find it, which I did.

Oh yeah, you also need to find a walkie talkie that might appear randomly when opening doors during scavenging.

The walkie talkie will appear next to your character portrait.

Once you find it, press the button "1" on your keyboard to activate the walkie talkie and this achievement.

Every second during the day that passes that has at least 1 survivor in base gives you "Search XP"
Its the empty bar up top below the day/night bar.
When you reach level 1, you get this achievement.

These are all the plants, you need to destroy them all without leaving the area, so no going into portals or dying until you get them all.

You will find locked chests in the areas where bandits roam, keep pressing down the interact button until it opens, do this 5 times in a single game on different chests and this will unlock. The chest respawn after a while, you can find more in the Fevela.
