Just be careful you don't get motion sickness easily. A portable Howitzer cannon. Primary fire rapidly shoots enhanced flak cannon shells, and alternate fire shoots two shells at once. Any Star Wars joke I could make here died with the old model. It's now a strange-looking saber with an energy blade, but the function is still the same.
Primary fire swings the sword, causing a lot of damage.
It's almost unfair. Alternate fire creates a small shockwave, pushing things away from you. You're supposed to be able to jump higher by pointing at the ground and altfiring while you jump, but all it did was push be backwards a bit. It's good for pushing people off ledges anyway. After using altfire, the sword doesn't respond for a second or two, which is very annoying.
