I'm sure just about everybody who has played GTA3 will remember the sign in Staunton Island which read "You weren't supposed to be able to get here you know".
Kuiosikle over at the GTA Underground has found that the sign is still there in LCS, except with a different message. He's also put together a detailed video along with himself narrating the route to the easter egg. Download the video from our database
The sign now reads "Hello Again" with a silly face under it. View bigger image.
This is also probably the first real easter egg to be found in Liberty City Stories, if you happen to find one yourself, be sure to post it over in our forums with any screenshots or videos.
Thanks to Laz for telling me about this nice find.
