2 Player co-op game

Hi, I'm currently programming a 2 Player coop game, this is the first time using networking code within Unity.

I've been looking into these on the Asset Store:
Ultimate Networking Project
https://www.assetstore.unity3d.com/#/content/234

Photon Unity Netowk
https://www.assetstore.unity3d.com/#/content/1786

(I would like to avoid purchasing any assets if possible, but will do if this creates the desired affect with little to no effort )

I have also been enquiring with members on previous projects how to go about this, we plan on focusing towards Non-Dedicated hosting.

Ill be posting my progress and any issues as I go along, If you guys think i've missed something or have any pointers to keep me on path, they would be greatly appreciated

Thanks
