Uh, so I guess this falls under balance.
I love to unclock the stun gun and stun baton. In fact, one thing I really consider an improvement to the genre that Xenonauts makes ( and most others don't seem to ) humans possess the ability to stun creatures availible relatively early, which seems fitting for a species who already stuns other creatures. Later on the upgraded stun pistol and stun rifle are cool, if not less useful by the time I unlocked them, but the lack of upgraded baton was a let down. I'm not saying you need to go in the full on antimatter zhanmadao samurai direction, or saying not to give us pulse katanas, but some sort of improved melee weapon like a stun polearm would be nice. It's always a moment that feels good to work towards unlocking, like when these sort of games let me upgrade the basic grenade launcher to an advanced grenade launcher.
