I was wondering if anyone could make a HDFirearm that shoots a arc'd bullet, which is where the actor who shot it, will teleport. Thanks.

I'm not a modder myself, but I'm sure the code from the teleport grenade from the Whitebots would have most of the relevant code that would be needed

I'm pretty sure CaveCricket did a mod that was pretty much what you are asking for.

Search for "A Collection of Crickets" or something like that, it has all the mods made by him, including this one. I think it was called the "translocator" or something, based on the Unreal Tournament's teleporting thing.
