The LSR44 provides a unique hybrid of submachine gun and sniper rifle. It's firing mechanism uses an electronic, rail-based technology. The design features open rails to vent built-up plasma to prevent damage to the firing system due to heat. In the campaign, the default firing mode on the LSR44 is fully-automatic. In multiplayer -- where it can only be equipped by the Scout class -- it is locked into a 3-round burst-fire mode. The railgun mode remains the same, though. The LSR44 is a very strong weapon, despite having no other attachments.
