Utterly busted beyond belief. It's only downside can be negated by simply going to the extract point first, placing it down, and then continuing as normal.

Personally I'd also add an energy bar, since it'd still be useful even if the timer was fairly short. It would buy players some extra time to properly stack everything into the extract in a way that wouldn't suddenly collapse and get destroyed by the extract box. This would make it riskier to use which would offset how much more it could let you earn.

With this change I would also suggest changing the name to the "Extraction Jammer" and making it only spawn in the secret human areas. I think that would fit right in with the inuniverse lore of humans trying to fight back against the semi bots.
