What's interesting in the Toxigun is it's size. Basically,
all my soldiers carry, in addition to their own normal guns and ammo and grenades, a toxigun with several clips in their belt. They use the normal Alien guns to fight and when they happen to fall on tough Aliens or Aliens with personnal shields, I switch to the Toxigun. That's a pretty easy and safe way to get personnal shields if you ask me.
