The Capsule Launcher would be an armor module which increases the rate you can throw capsules and possibly also increases the robot follower count, the range you can throw capsules, or the area in which robots engage enemies around you.
- +100% Capsule Deployment Rate (with one module, you can throw 2 capsules per second, with 5 modules you could throw 6 capsules per second)
- +10 Robot Follower Count
- +20% Robot Engagement Area
With a bunch of these puppies in your armor you could lay down the hurt even on the highest biter settings, the cost in terms of capsules would be horrendous which is exactly why it would be an awesome option for the proud owner of a end-game factory.
