Rakghoul transformation, laboratory routes and a purge mechanic.

STORY / VETERAN / MASTERFOUR-PLAYER CONTENT11 NAVIGATION STEPS

01 · IMPERIAL FLEET

Where to start Trial and Error

On Imperial Fleet / Vaiken Spacedock, find the Combat Training sector and its glowing blue Uprising table. Choose the Story, Veteran or Master terminal, then select Trial and Error. Accept or share the same difficulty with your party; choose a matching Weekly if desired. Use the shuttle icon beside the mission in your quest journal to enter, or use the shuttle in Inventory → Mission Items.

Not a solo Flashpoint: Story means easier four-player content, without the scripted Flashpoint combat support droid. Manual group entry is available. Activity Finder playlists have changed between updates; the Fleet mission table remains the dependable place to select any named Uprising. If starting a new Uprising after abandoning another, the group leader can right-click character portrait → Additional Commands → Phase → Reset All Active Flashpoints, but this loses progress in the previous phase.

02 · OBJECTIVE-BY-OBJECTIVE ROUTE

Where to go, what to click, and what comes next

Follow these numbered steps in order. Controls are called out where defeating enemies is not sufficient to move the quest forward. Do not confuse optional achievements with required doors or boss phases.

  1. 01

    Breach blue first door

    RIGHT-CLICK GLOWING BLUE DOOR WITH GREEN CIRCLE and survive the short breach timer.

  2. 02

    Defeat Marlon Fenn

    Kill smaller enemies and INTERRUPT ROCKET PUNCH.

  3. 03

    Go SOUTHWEST to elevator

    After Marlon, IGNORE BROKEN NORTH DOOR; the route continues toward southwest elevator.

  4. 04

    Optional: Rasher Poth and Rak-5

    Enter FAR WEST SIDE ROOM, defeat optional RASHER POTH, then CLICK BLUE RAK-5 DEPOSITORY to gain temporary Rakghoul form.

  5. 05

    Ride elevator toward Icarr and Nyris Ko

    Follow main lab route, watching LIGHT BLUE TRIPWIRES in their room.

  6. 06

    Defeat Icarr and Nyris Ko

    Avoid tripwires and GREEN PUDDLES. In Master Nyris's Irradiated Blood is dangerous; kill adds before the larger enemies if needed.

  7. 07

    Optional: EX-26 and NEWT flamethrower

    After the pair, enter NORTH SIDE ROOM to fight optional EX-26. RIGHT-CLICK BLUE EXPERIMENTAL WEAPONS CRATE to obtain NEWT temporary flamethrower.

  8. 08

    Disable PURGE electrical traps

    Stay between ZAPPY RED CIRCLES or on RIGHT LEDGE. DESTROY BOTH GLOWING BLUE CONTROL PANELS near next door to turn off the traps.

  9. 09

    Activate final four pillar buttons

    In ALIRRA SEMHESS chamber RIGHT-CLICK FOUR BLUE CONTROLS around interior pillars ONE AT A TIME; brief electrified shield prevents doing them simultaneously.

  10. 10

    Defeat Alirra Semhess

    She changes to RAKGHOUL form. Avoid GREEN CIRCLES, PURPLE AOE and mines; on Master VIRULENT TOXIN needs a cleanse very quickly.

  11. 11

    Exit Area

    Main completion doesn't require Rasher or EX-26; leave once Alirra is dead.

03 · ENCOUNTERS IN ORDER

Named encounters and fighting priorities

  1. 01 · Marlon Fenn
  2. 02 · Icarr and Nyris Ko
  3. 03 · Alirra Semhess

The step-by-step route above explains the mechanics alongside the point where you actually encounter each boss. Encounter labels can include a wave or objective rather than a conventional single boss.

04 · TROUBLESHOOTING

When the mission will not advance

Where do I start this Uprising?

Imperial Fleet → COMBAT TRAINING → GLOWING BLUE UPRISING TABLE → pick Trial and Error on the correct difficulty terminal → click the SHUTTLE ICON beside the quest.

Why does the next door not open?

Check whether your current objective requires a remaining enemy wave, a glowing blue console, or a temporary ability. Work through the numbered route instead of attempting to skip the locked door.

Is Story mode a solo story instance?

No. Story is the easier FOUR-PLAYER UPRISING difficulty; experienced players can sometimes solo one with an appropriate companion, but this is not the supported Solo Flashpoint style.

Where are the original in-game screenshots?

The original source guide linked at the bottom includes game-client screenshots for this Uprising. This IDS article does not substitute an invented map.

Original maps, encounter screenshots, and verification

Read the original illustrated source if you need to recognize a particular blue console, grapple point, arena entrance or mission item. IDS directions are research-based and should not be mistaken for hands-on testing in the current game client or a substitute official map.
