I'm looking for a engine to work with but...

[Irrlicht Engine]

I'm looking for a engine to develop off off, but I want something better than Quake III but still a fps. Is there a game that is a open source multiplayer FPS which uses the Irrlicht engine?

Who said you needed to use Quake III? Those maybe be what the demos show, but I am certain that this isn't all Irrlicht can do.

First off you are probably going to want to look up ENet/IrrNet/IrrNetLite, and use one of those for networking with Irrlicht. And you will also probably want to use the IrrAI library by JP. And there are loads of other things that can help you along the way, you just need to do some searching.

I'm looking for a open source multilayer fps because I want to skip a huge part of the development phase. I'd go with Quake III before adding six months to the process. I'm just wondering if there is some pre made multilayer platform that is usable, I'm not going to be making a fps so the network doesn't have to be quite as fast. I'm looking for a already integrated source though. Is there one?

Not that I know of.

I don't know of an open source one either but you can take my engine to start off and add net support if you really need it that bad.

Or you can start with IrrWizard which is much smaller then mine but the same idea should apply there too.

Either case you have to develop it for yourself (Until I add net support to my engine myself )

how about the Cube engine? I haven't used it though. But it's probably better than Quake III... (at least at graphics)

There's an open source game engine I don't know of .. I feel a great disappointment from Google, I had to work so hard having only IrrWizard as the reference to learn from..
