i'm going to list some easter eggs ranging from small to big and just post theories on them or extras....
Starting off ..i'm sure everyone knows finding all 115 rocks gets you the song .... if not post below
Another one that i've been thinking about is when you open the door next to the stage that goes up the emergency like stairs and goes into a room that has a chest of letters and some are spilled....i looked at this and one of them is XII which made me think something happened on round 12.... also next to it ...it'll say something like MANHATTEN DOWN which is the rocket/ nuke experiment back in sometime i forgot...but i thought about the one rocket that takes off in the Presidential room when you go through the teleporter...i've been trying to activate the rocket(since it has taken off before) but i've been getting unlucky...seems the game was designed to do this on purpose.....my group of 4 we had 5 crawlers and when we went through the teleporter that round they all died....and it happened a second time on round 12 ....maybe we need about six because manhatten down is spelled MANHATAN DOWN
it's missing an extra "T" and "HATAN" in portugese means "six" ??? maybe we need 6 crawlers on that round to actually test this theory ??? ....also in the "down" part the "ow" is connected with "Now" so it's like "Down Now" hmmm...that room interests me i've been doing more studying in that room
Next topic is also the room with the beating sounds in other room next to stage...there's a green glow and a beating sound...i've thought this was morse code at first but haven't really found anything that makes sense when i listen to it carefully and use morse code....But one time when i was going up emergency staircase...(same from theory above with letter room) i looked down on the side and noticed one of the monkey capsule (or human capsule..not proven exactly what it is yet) in a suitcase so i thought maybe in the closed suitcase that seems to have that beating sound ...is a capsule that's open and one of them is trying to get out...not sure though
Another topic is the writing on the walls ....and Grim Reapers...i don't know what exactlyt he Grim Reapers are for but there's quite a few of them and i noticed one on the Campaign mission "Project Nova" when your running of the ship you can see it in the cracks... but yea they are scattered throughout the map..but mainly in the beginning areas. also the "Samantha Emilia Abigail" with a heart and the JD initials next to them are found in room with beating suitcase....just mainly little girls name but maybe we are missing a deeper meaning... Also the writing "Knowledge itself is for the taking" hmmm idk what that could mean besides the radios(that are found in main chandelier room and outside area out on a building ledge) and also the film reels. Another writing is "Beware the 6!" many believe it's just talking about nova 6 (the crawlers) but i feel as though it has a deeper meaning because this game is focused a lot around 6 ! i've noticed in the map "Five" that when the teleporters cool down and you can see numbers turning, the only numbers not turning are the 6's ... also there seems to be only 6 grim reapers on that one map ...and let's not forgot "HATAN" which means six !!!! any theories....
These are mainly all the main easters eggs/secrets that i've wanted to go over ....post below about theories regarding wht i've said or ...the picture frame with nothing in it or character's quotes that they say throughout the game or any other details !!!
p.s. I
*UPDATE* just wanted to say that also i've noticed..i activated the missle in the presidental room in the teleporter and like either the next round or the one after i went back and it was there again...and i couldn't get it to take off .... hmmm ???
