How do I combine meshes

Chasmalim

I have a model with several different meshes on it and I would like to combine the meshes to make it a little easier to use in autodesk and udk, I intend to use it as a game character and it doesn't need removable items.

Assuming you have a Game Developer License that covers the products you wish to use you would need to use your modeller to combine them, removing unwanted portions and if need be bridging or otherwise filling any gaps.
