Messages

Messages are writings in ASU, mostly found as blood writings on walls.

Non-Hidden
Non-Hidden messages are messages blatantly shown that can usually be seen during normal gameplay.

So Much Blood...
On a wall near the spawn in the Boiler Sector, you can find a message at the back area reading, "So much blood, so much death..." The first "much" is mostly covered by a crate however.

Please Come Back...
Another location is near the Dead End sector, on a wall opposite of ways into the rooms. It reads "Please come back..."

Subscribe To MGG
Yet another location is a easter egg to the main developer, MysteriousGamerGuy, on a hall wall in the HI wall room. It reads "Subscribe to MysteriousGamerGuy!"

Not A Sponsor
A new message as of the 1.0.1 update was put into the game near a just as new Mcdonald's poster. It reads, "Not a sponsor..." referring to how the main dev, MGG, loves Mcdonalds and that he isn't really sponsoring Mcd's, he is just showing his love for it. It is also just a joke revolving around the poster's existence itself.

Hidden
Hidden messages that are far more hard to see or discover than others. They could be hidden behind objects, out of bounds, or even through secret puzzles.

Spotsdog
A hidden message is behind a crate in the swiss cheese hall area. It is a bump on the wall with the word "dog" next to it. This is a reference to the dev, Spotsdog, as reading it out in a way says, "Spot Dog" or "Dot Dog."

Trivia

 * Otherwise inferred by reading the "So much blood" message, there is no blood or corpses to actually be found in game, aside from the blood writings themselves.
