Thank you. I missed that one, because when looking at the game page I missed the part where it said "Battlezone: Combat Commander is back" (the only indication on the gamepage afaik that this is a remaster, if someone isn't familiar with the series). Added to the gogmix.

OK. Updated.

By the way, is replacementdocs down or is it just me?

It's down:

The Trine 2 manual link appears to be functioning.
That manual appears to be the same pdf that I received in my email when I requested the manual directly from Frozenbyte.
https://www.gog.com/forum/trine_series/need_help_with_a_trine_game_email_the_devs
It is interesting that this manual pdf is considered low quality according to post4.

According to the reply from Frozenbyte, they are not planning on adding the manual anywhere, because the game is old and no one else has asked about it.

Yes, the Trine 2 manual link is OK. It's the Trine manual link that's broken. I've corrected that now.

The reason these manuals are described as "low quality" is because they are clearly just plaintext with images added. not real physical manual scan. You could clearly notice the difference when Trine 1 manual was available.

Unless someone can confirm that the Trine 2 manual is the only type that was ever available (i.e. the boxed copy cam with one exacly like it) - see Open Questions - I'm going to keep the "low quality" note.

As I said last year, GOG received, at least, a printed German version of the Battlezone 2 manual. See their Instagram account (30th pics).

They are different.
The manual in the URL above (ENUK) is COLLECTION manual for console version.

GOG's The Secret of Monkey Island Special Edition - Manual.pdf is PC version Special Edition manual.
GOG's Monkey_Island_2_Original_Manual.pdf is original DOS version manual.

The manuals are from the PC DVD MI SE COLLECTION.
PC Windows and no console
See my image from the game.

Edit:
GOG's The Secret of Monkey Island Special Edition - Manual.pdf are ingame screenshots and no official manual

Thank you. Which GOG game would these correspond to? (Sorry I'm not familiar with the Monkey Island franchise). Is it this one?

I have the Collection as well. It includes the following games:
https://www.gog.com/game/the_secret_of_monkey_island_special_edition
https://www.gog.com/game/monkey_island_2_special_edition_lechucks_revenge

Thats correct

Thanks. So just to clarify, the above game's gamecard says it already has " Special Edition manual". Is it different from the one KingCross posted?

Yes.
See "Edit" here

Thank you. Missed that edit. Both added now.
