Description:
This gun is made for special force groups or assassins. It's primary weapon is a particle beam rifle with an effective range of 1200 meters. It doesn't have the longest range for a sniper rifle, but it makes up for this by being able to fire a bolt that is invisible. (Source for this technology) The drawback to this ability, however, is the canisters which hold the specialized gases needed to make the bolt invisible, are very expensive. At 1,000 credits each, you won't be taking this to the range just to go plinking around.
The other special feature to this weapon was the dart gun that it possessd. Unlike pre-filled darts, though, the darts loaded would be empty. The canister with the biohazard symbol on it contains several vials (4) of different compounds. When the shooter is ready, he/she simply chooses which toxin/tranquilizer he/she wishes to use, and the dart is then injected. The dart gun is now ready to fire. Although this method grants the user a lot of versatility. The dart gun is very slow to fire. Requiring a minimum of 5 seconds in between shots, to reload a new dart, and inject the selected toxin/tranquilizer.
Strengths:
Versatility
Invisible particle beam
Weaknesses:
Low effective range for a sniper rifle
Slow reload time with the dart gun
Expensive to own and operate
Cannot fire at redirection crystals due to lower power yield in the shot
