Game Patching Help

Don't hate since i am not sure if its the right forum i placed it in, but i guess maybe ^^

Okok, i need some sort of Game Patching module, either directly for Unity3D (Prefered), or external software that can get the job done.

Since i am developing a Multiplayer game, i would like users to recieve updates and automaticly download them, before they can play the game again, are there any good ways for doing that?

I have seen the M2H Patcher, but it seems a bit expensive, or is that just me that are a cheap ass? ^^

 

have a look here http://forum.unity3d.com/threads/151893-Crafty-launcher-and-patch-system-for-Unity-and-others

 

Thanks element, it was just as i wanted it. ^^
