In the power room there is one green letter, in the trailer under that u can pick a raygan and presumably upgrade it like alpha omega

Yeah I noticed the green letter in the power room is a Greek letter, in my games I saw Pi, Theta, and Lambda, I would assume there's probably one more but after looking around the map I have not seen any sort of numbers/words/letters which go with the Greek letters, so there definitely seems to be something we're missing with this side EE. The trailer makes it look like they're only regular Mk 2's, but whether they're upgrade-able or not, the free Mk 2 will be so useful.

ok so it turns out someone figured it out, i made a discussion post on it but here's how to do it: after completing the main easter egg and your in night time youll notice all the small tvs are now on and displaying a symbol, return to the power room and youll see a green symbol, go around the map and turn the tvs onto the symbol displayed in the power room. TV 1 is in the garage, tv 2 is in the area to the right of jug its sitting ontop of cardboard boxes, tv 3 is by the burning tower near quick revive, also on boxes, and the last tv is to the left of pack-a-punch. then once all 4 tv show the symbol return to the power room and youll receive the raygun mk.2
