a vote option for CTF without the grappling will be great idea

why no ctf :( this will be fun if we can add insta bounce for railgun item + adding rockets weapon for CTF on DivineIntermission map that will be awesome .

It was on QL practice, true hook and rail.

Unfortunately that's not possible.
In QL you can change a lot about the gameplay by tuning existing cvars, but there is no real modding ability. That would be required to add a true off-hand-hook similar to q2 lithium

Is it possible to create hook as a none weapon? to combine rail and hook?

combos are pretty easy to do when you have those key binds.
just release the thumb button (-hook triggers) and press mouse1. it's an instant switch from hook to firing a rail.
only thing you cannot do is fire while you are camping on the ceiling with the hook

damn shame, got it on my serv now. but need hook and rail combo :(

You can connect to beham.biz:27960 to try it out (hostet in germany)
or 45.79.100.154:27961 (US west coast) for servers which run this mode.

If you have extraQL installed and the InstaBounce userscript enabled, it will automatically bind your mouse buttons when you join an insta bounce match - and restore your old config when you leave.

no, the hook is a weapon and you can only have one in your hand at any given time.
The workshop item adds a "ibounce.cfg" script which you can /execute.
That will bind mouse2 and mouse5 to aliases which switch weapon + fire when you press the button, and switch back to rail and stop fire when you release the button.

When you start a match with any of the ib_* factories (e.g. /map campgrounds ib_ffa), it will reduce the weapon switch time as much as possible so the switch feels almost instant.

can we use hook and rail at the same time? So far not been able to bind it this way
