Grand Theft Auto Online, the official multiplayer mode for GTA 5, will be revealed today at 3pm - and you can watch the trailer right here on VideoGamer.com.

We were given a few seconds of GTA Online footage back in July with the release of "An Introduction to the World of GTA 5". The video ended with the playable character standing in an apartment block overlooking Los Santos, as planes, helicopters and cars are seen through the window.

GTA 5 launches on September 17 for Xbox 360 and PS3.
