Killing Floor's New Achivements Icons Revealed

Any guesses what they are for actually before the Killing Floor Summer Event starts?



My guesses:

1. It looks that there will be 2 Maps Confirmed Normal and KFO for sure..

2. New Playable Character pobably unlockable after getting some achivements?

3. Limited Time Achivement?

4. Welding Achivement?

5. Collectable Coins Achivement?
