This isn’t totally about the amount of hunters deployed being overpowered. It is and there is already a thread which addresses that although I might touch on it. I really like the idea of the harvesters being able to deploy Hunters. It brings a whole new element into the game and really makes it more interesting. However; the first time I saw it, I thought it was a glitch. It just didn’t look right visually. From my memory it looked they were being spawned like ticks and about the same size, and then rapidly grew to full size. I could be wrong, going by memory, but it definitely did not fit the more realistic existing art style of gen zero. So much so that it made me think something had gone wrong with the game.
For a harvester to deploy hunters, they would need to come out of an appropriately sized container(s). Frankly, I just don’t see enough room on one to carry much more than 2 or 3 containers. I also think that is about right as far as game balance goes. Once those 2 or 3 are deployed, that’s it. They don’t magically respawn in the containers. The different classes could have different amounts of containers from 1 to 3?
This should solve the OP problem and the immersion breaking visual at the same time.
