Has anyone obtained the Croc mask yet? It's the only one left for me.

Played the whole game twice and just couldn't find it. Any help would be appreciated.

I'm here for exactly the same reason. I've trawled every level. I didn't find the rat mask until I replayed the level before 'Trauma' and the logic of where I'd find it struck me.

FYI it's actually an alligator, for what it matters. I thought Croc too, but the Steam edition has an achievement named after it. Makes sense, given that the game is set in Florida.

Where would we find an alligator? The achievement is named 'sewer alligator' or something, so... Perhaps in a toilet?

Toilets are the easiest rooms to check, the bright white tiles and uniform fittings make oddities stand out, and I've just not seen it.

Haven't found the mask yet either.

SPOILER ALERT just in case someone who hasn't finished the game reads this:

Do you get the "Sewer Alligator" achievement after finding the mask or doing something with the mask on? The only sewer in the game is at the very end with the "janitors" in it, but I couldn't find it there at least.

Haven't found it either, it must be really well hidden to be an achievement, but according to Steam at least someone has unlocked it. I backed up my saves.dat file and edited it to see what the mask looks like. It's called 'Jones' and its effect is 'More gore'. It's bright green with purple-pink eyes. None of those facts have helped me find it yet.

:D +1 Finally got all the masks now!

Damn, dude. That was obscure. I had been curious about that manhole but assumed it was nothing because every single other level contained -nothing- outside the building :\

I feel.. wrong, for not finding it for myself. Baaah.
