Completing Tachyon’s quest awards GUINEA_PIG. The official badge description confirms that completion objective, but does not describe every stage or promise a health increase.

Before you start

Open the current task offered by Tachyon and record its requested item or target before leaving. Use the location and quantity shown by that task, then return to the relevant interaction to check whether the objective advances. Verify the named badge after the final completion; collecting an item without the task accepting it is not evidence that the whole quest is complete.

What the description does not establish

The old enemy-count tables, phase count and leaving/death reset rules have not been verified for the current quest. Do not combine unrelated boss badges into a Tachyon checklist: THE_POINTMAN names Gilbert, while COMMANDER names Chimera. Those separate badge objectives do not prove that Tachyon requires both bosses.
