You found the Rizzo's Spectrum Gatling sealed inside a case inside the RR&DD Labs' Head Research Lab. The terminal said the weapon required all 8 flavors of Spectrum Vodka before it can be used.

At the End of the Spectrum Walkthrough
You will need to collect all 8 flavors of Spectrum Vodka. These are found in a variety of places all over Eridanos and some can even be purchased from the shops and bartenders around.
The easiest way to complete this is to go to the Distillation Station. From the room with the giant Rizzo's mascot head, take the Southern door which leads to a bar. All 8 flavors of the vodka will be scattered all around the bar.
Once you've collected all flavors, head back to the terminal at the RR&DD Labs to complete the task and collect the Spectrum Gatling Science Weapon.
