Hey, so I just started playing and I must say, it's a lot of fun! However, I've encountered an issue that's either a noob not understanding how it works or a bug. When are you supposed to get your first stun weapons? I had the research notification pop up that I should have the beat-sticks available and start capturing these alien bastards, but I can't find them in the equipment screen. I checked the videos so I know right where they should be, but no sticks.
