Down the Chain

Standard Sleeper Cache

Tier 2 of 3 · scan L4High SecurityLow SecurityNull SecuritySleeper

The middle sleeper cache — the full hazard set (explosive hacks, clouds, proximity triggers, sentries) at higher stakes than the Limited. Read the room layout before touching anything. The killer here is the sleeper sentries — they can alpha an exploration frigate, and 'sitting still for 30 seconds in the end room' is the canonical death. A drone bay matters: players use drones to clear sentries (Astero/covert frigates fine; T3C/Stratios for comfort).

What players report (community corpus, support-counted)

  • Failed data hacks raise an alarm level; at the threshold it triggers 'cleaner' gas clouds that can kill you before you finish warping out (support=2).
  • Bring a T2 Data Analyzer — for some security cans a failed hack is reported as effectively lethal (2025).
  • Safe partial clear: take the three near depot cans, hack the Defense Alarm Unit fast when the mangled depot spawns it, and skip the back room — it can't be run with the sentries alive on a light hull.
  • First can-set can be taken with NO aggro and no tank if you touch nothing else.
  • Ships that work per reports: T1 explo frigate at the ragged edge, Astero comfortably, Stratios/T3C for the whole site; Navy Apoc/battleship overkill also attested.

Payout B Community-corroborated

Player-reported average ~100-125M ISK per run (support=3, 2020-2025), plus polarized-weapon and storyline BPCs whose value swings from junk to hundreds of millions.
