I don't think we'll be taking on an EE3 any time soon as we're currently busy developing in other areas. Also your model could use a little more work, the geometry is a little crude at the moment and could use quite a bit more detail to get it up to the same level as our other first person perspective blasters, there is also the question of texturing as well. What I would advise you to do is continue developing the model and we'll take a look. Then if an opportunity arises when we can look at developing this further we may look at where you're at with your model and consider it for inclusion.
Thanks for your interest in developing assets for First Strike. Also consider applying to be a member of the development team if you're interested in working on any further projects. Check out this post for information on how to go about doing that:
