Here is a little tut on how to start WarRock without the updater.
It is much quicker and even works with hack hooks!

1) Right Click on your desktop.
2) Go to New > New Shortcut
3) A box will appear
4) In that box copy and paste this into it:

"C:\Program Files\GamersFirst\War Rock\system\WarRock.exe" 0 0

5) Run WarRock!
