Tau Cannon (Universal)

find in category "Universal Weapon"

a gauss gun，just like half life's，but have some different
press E to switch reflex and not reflex
left click fires beam which can reflex in some angle.
damage is 50

right click to fire charge shot，can max charge 2 seconds（cost 10 unit ammo），has 75 damage per unit，then，release to fire，this charge shot would push you back，so you can use it to gauss jump，and the beam can also penetrate some human targets.
you can keep pressing the right click，although it have charged max，it wouldnt hurt you.
charge 1-9 unit ammo would cause 75-675 damage，but a fully charged shot has almost infinite damage
