Eh, it could be used for suicides, or sniper rifles.

I started the habit of committing suicide when I finish a mission.
Apparently Dear Sister reloads itself on the ground.

All weapons reload themselves if you drop them, oddly.
And yeah, the offsets are a bit strange, so the bullet has a tendency to actually shoot its owner. This also happens if you're too close to your target. This is all because of how the "collision detection" for the bullet works, e.g. trying to find the closest actor in a range. Until there are more accurate techniques for checking collision in CC, we'll have to stick with this

this gun is jokes...somehow a zombie managed to get hold of it on zombie caves and shot me, a fully armed space marine, dead. the music played and i cried a little. after i had laughed for about half a minute though, hahah

I just killed myself with this by using my portal gun

it doesn't seem to work all the time.

now all i need is a flamethrower that sings "ring of fire" by johny cash

And everytime i used it.. it flew right off the hands of my actor..

It's supposed to do that. Can't remember why. The reason's funny though.

Robo, if it penetrates the actor and goes through, it will not work unless it hits terrain very close to the actor. The newest version should fix that problem, but you may have a problem shooting harder actors, like a brain case or robot.

And the gun flys out of your hands because you are in shock that you actually shot someone

Please tell me firing this slows down the game for a period of time. It better.

It does.
And yeah, it doesn't work if it penetrates actors. I tried to fix that as best I could but it's not entirely perfect.

Of course it slows down time! It wouldnt be dear sister if it didnt slow down time!

That's what happens in the Dear Sister videos, someone reads a letter, that person shots their sister, it plays that song, and then goes into slo-mo.
