All questions are related to the game.

1) Upgrade Towers 1000 times. (First letter - upper-case)

3) Shhh, This is a secret achievement, can you unlock it? (First letter - upper-case)
4) Fifth supported language that has recently been added. (First letter - lower-case)
5) Eleven towers have this letter in their name (lower-case) UPDATED changed 10 to 11, sorry.

Ends in about 3 days.

Good Luck.

EDIT: For question four, it's possible that different languages of steam/website will show them in a different order. There are only six languages listed so just try them all. Sorry about that. :(

Update: All finished now, the answer was this
