I played a helluva lot of Left 4 Dead back in the day on a unpatched xbox, so I missed this graffiti when i swapped to pc...thanks pard. I knew it was different

this is not obsolete :P

Is this a obsolete mod after The Last Stand Update?

Apparently, Gamers 4 Croydon ran directly against the R-18 classification policy's main opposition, Michael Atkinson, back in Australia.

Whilst they may have lost the election, their contributions towards R18+ policy had a lasting effect, which even saw Atkiinsons eventual resignation.

As a thank you, Gabe Newell and Valve have placed an ‘easter egg’ graffiti replacing the original one.

I believe that user (or group?) assisted with a exploit fix or something, so they changed the graffiti as thanks.

why did they change it to g4c?

Currently L4D2 has the graffiti from the first screenshot (Gamers 4 Croydon). This add-on restores the graffiti to that seen in screenshot 2 (Not a flu).
