But Kosta already proven putting it on the site!

Maybe I'm wrong. Can someone of admins answer if Keen 6 is available for download?

It isn't.

The Keen games aren't even that hard to find if you look around - they're not bad as games but it's often a lot of saving/reloading everytime you die. Aliens ate my Babysitter was one of my first shareware games back in 1993! I didn't even know what a demo was back then.

Commander Keen 1: Marooned on Mars --- 1990 --- Apogee --- SOLD
Commander Keen 2: The Earth Explodes --- 1990 --- Apogee --- SOLD
Commander Keen 3: Keen Must Die! --- 1990 --- Apogee --- SOLD
Commander Keen 4: Secret of the Oracle --- 1991 --- Apogee --- SOLD
Commander Keen 5: The Armageddon Machine --- 1991 --- Apogee --- SOLD
Commander Keen 6: Aliens Ate My Baby Sitter! --- 1991 --- FormGen --- ABANDONWARE

Keen 1 and 4 are shareware, however they ARE the full games, so technicly,
they're abandonware.

Oh and for the record:
