Several videos of the Battlefield 3 Alpha have been leaked onto the web ahead of the game's closed beta in September, with a fresh batch of details about the game's new sniper rifle and a number of other weapons.

Among the videos is a seven minute long montage containing raw, first person footage from the game's multiplayer mode.

The build of the alpha in question looks roughly the same as the one previewed at E3 2011 and elsewhere recently.
