OP recommended I share my opinion on the new tranquilizer here:
Anyone else disappointed by the tranquilizer pistol in Hitman 2? After unlocking the Kalmer 1 (mastercrafted tranquilizer unlock in Whittleton Creek), I had hoped it could serve as my primary handgun when going for silent assassin.
Except it only comes with 2 rounds!
I understand it should have a low ammo count similar to the Krugermeier (even though picking up a guard’s handgun would solve your ammo problem). I’d accept an ammo cap of 5 to 10 rounds, but 2 is too little. The gun is functionally worthless as a result. In practice, 2 tranquilizer darts is the equivalent of carrying two blunt objects. Agent 47 can carry an infinite number of objects to throw at people’s heads, so why can’t he start with more than 2 tranquilizer darts?
If that wasn’t bad enough, there is a bug that affects tranquilizer ammo. If you reload a save during a mission, any spare tranquilizer ammo disappears. That leaves us with 1 tranquilizer dart to play with. Completely cripples the gun.
Maybe if the Kalmer was a gadget, I’d be fine with the ridiculous low ammo count. However, it takes the place of a sidearm during mission planning. It should at least carry the same amount of ammo as the Custom 5mm.
