Once you attain the OMEGA Protobuffer variant (Shoot the protobuffer box inside of the press box)

Underneath the stadium (The first lockdown area before the bossfight) you'll see 2 tesla coil, metal things dangling down from the ceiling, with white orbs in them

Shoot both of those orbs with the omega protobuffer, and you'll get a phone call immediately from Press box guy "Bro did you just reinitialise the 5G tower..."

After that you can do the initial lockdown / hard bossfight at any point

You activate hard more AFTER doing the bossfight the first time, I just realised I forgot to say lmao

what are even the ee steps i thought there was no ee in this map yet?

The Easter Egg quest is not implemented.

Currently to access the boss fight you need to build all the variants of the Wonder weapon, then the "under the stadium" area will open, you will be able to start a lockdown in that area, once this is done, you'll head onto the field and do the normal boss fight

then after the bossfight, you head into the press box, shoot the box for the OMEGA protobuffer variant, and do the quest for that

Then when you have Omega, you shoot the 2 white orbs under the stadium with it, and do it again, but on hard mode
