Grand Theft Auto 5's online mode, GTA Online, will be officially unveiled in a new video at 3pm BST today, Rockstar has announced.


We were given a short tease of GTA Online back in July with the release of "An Introduction to the World of GTA 5". The video ended with the playable character standing in a high-rise apartment block, as player-controlled planes, helicopters and cars are seen through the window.

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