I don’t think any of the projects support melee out of the box but you could add it yourself. It’s something I need to do eventually for my project but until I’ve done it, I don’t know if I can give any advice on that.
In the mean time you could start with your third person shooting by downloading the shooter game template, and edit a few things with “playerpawn” in the content browser. Start by changing the first person mesh to the third person mesh (http://puu.sh/aD2jz.png) and changing the first person animations to the third person animations (http://puu.sh/aD2jQ.png). Then add a camera component and position it behind and off to the side of your character. That should get you started.
