Escape to game menu and hit ~ , not on game running .

Hi Àzure,
actually, it should work during gameplay, too.

key for console is tilde (~)
It is located right above tabulator and to the left from 1 key.

thanks for answering but nothing mentioned works

Care to tell the keyboard layout you use?

I use an AZERTY keyboard, Belgian (point).
The key above the TAB-key is ², but that one doesn't open the console in-game.
My tilde key is accessed by pressing ALT GR and =, but, well, it is no surprise that this method doesn't work either.

Normally you can bring the console at the main menu, so I suggest going there and trying every key.
On my (azerty) keyboard, only ² brings the console.

So on a UK English QWERTY keyboard what enables console?

It sure isn't ~...which is to left of ENTER and above right SHIFT
