Back in May we recorded videos of all the main storyline missions in GTA IV, which we were planning (at some point) to put on the site. However, due to various factors this became delayed, and we have only now managed to get around to doing it. The videos can be viewed here in our gallery. At the present moment roughly 75% of the missions are available, and over the next few days we plan to add the rest, along with videos of all 50 unique stunt jumps. All videos were recorded on the Xbox 360 version of the game and uploaded in HD. Enjoy.
