Game is good so far and you guys have been pretty great with bug fixes. I do think the Orgyn should get access to missile launchers as another explosive weapon options. There are bunch of missile launcher you can give them, preferably you should give them missile launcher that can shoot multiple rockets but it is weaker in terms of explosive damage when compared to single shot grenade launchers.

Now when I was playing I could not help but notice that in one of the conversation between player characters they mention ratling snipers. That would be a very cool class to add to the game and would add another abhuman race to choose from. This would be the only class that should have access to sniper rifles with high zoom optics. It will also give teams the ability to counter snipe enemy snipers. Though I do have feeling you guys may be saving ratlings for future DLC content.
