I've been playing a bit on a pub server with some new ET mod called no quarter. It has some funny addons including shotgun and panzer cam.
That is you have a tiny picture in picture looking thing showing your panz rocket as it flys it's path. You can also make your in flight rocket turn corners and whatever as it travels chasing a target.

I haven't figured out exactly how to do that.

Anyhow the server is at:

(HAM) No Quarter Rocks
66.240.211.100:27960

I think some guys had steering on their panzer shots in ET Pro Played it a bit as well and yes, a pretty fun Mod.

It's a bit scary when you see the panz coming at you around the corners you don't know where to run

Its wierd because its flying around and you dont know if its friend or foe either

Yep it's pretty crazy. There's a few things about the mod that make it interesting to me. I join that server most times if I see any people on it and run from panzers..
