This GTA: Liberty City Stories glitch allows you to freely control the Maverick (the only possible cheat-free method to grab it), in the mission False Idols.

The whore in the back of helicopter is so intelligent that she keeps walking straight away till she falls. Try it if you didn't already :razz:
You can get into the underworld and land over the Porter Road Tunnel's not finished part (Staunton one) and run over it.

In the parts where the mission you blow Fort Staunton, you won't see them completely, but they are still there and solid, it's hard to jump over the shafting machine and then into the tunnel as some parts are invisible and you can fall into the underworld again.
It's funny to fly over and see how finished the medium-height buldings' roofs are.
