Grand Theft Auto IV (GTA 4) Glitches: Totally Under Map Tutorial

Grand Theft Auto IV (GTA 4) sandbox-style action-adventure video game: Totally under the map

Can be done on single and multiplayer mode. It is easier to do on the single player, make sure the left door is open and the right one closed. Then ram your car on the open part and if done right, the container will start to spazz out and then all you need to do is walk inside.

Sometimes it will shoot your guy up in the air, sometimes really high and sometimes not too high. But if you crouch and walk in, you will fall under the map.
