The Disk Launcher fires a rapidly rotating disk, similar to a saw blade. The Disk Launcher has a tendency to dismember opponents and the disk will rebound to one other target if they are close enough together. The Disk Launcher possesses a melee attack where Sam swings the weapon downward with the disk spinning in place but not actually firing, similar to a buzzsaw. The upside of this is that unlike the standard melee attack, the ARS suit will not overheat if the attack connects. The disk launcher is a very reliable weapon with good damage and excellent melee damage. The only downsides are its short/medium range and its slow rate of fire.
Fully upgraded, the Disk Launcher receives a stock and the white ribbed part below becomes a dark grey one.
