Quick answer
Load The Library on Normal at Rally Point Bravo, run into the nearby Combat Form group, shoot each weapon-side arm first, and aim slightly outside the hand so the Assault Rifle does not kill the torso too early. Restart the level after the local group is gone and repeat until 100 Flood parts have been dismembered.
Guide briefing
Disarmed: Repeat the Rally Point Bravo Flood Encounter
The source turns Disarmed into one repeatable loop: enter The Library at Rally Point Bravo, disable weapon arms without killing the torso first, then reset the same nearby encounter. The frames show the exact corridor, target profile, and Combat Form group used by the route.
Before you start
- — The Disarmed achievement or trophy has not yet registered 100 Flood parts.
- — The Library and Rally Point Bravo are available in mission select.
- — Use Normal difficulty and keep the Assault Rifle for controlled bursts.
Applies to
- — Players who did not unlock Disarmed through normal campaign play
- — The Library on Normal difficulty from Rally Point Bravo
- — Achievement and trophy versions that require 100 Flood parts
Target
Reach the repeatable Rally Point Bravo Combat Forms
- Checkpoint
- Disarmed still needs progress toward 100 Flood parts.
- Landmark
- The Library corridor after the Rally Point Bravo spawn, with blue Forerunner lights and the first Combat Forms ahead.
Do this
- 1Load The Library on Normal difficulty and choose Rally Point Bravo.
- 2Run forward and take either side of the corridor until several Combat Forms jump into the nearby encounter.
Confirmation
The objective reads Explore the library and the first Combat Forms enter the short blue-lit corridor shown by the source.
Target
Remove weapon arms without killing the torso first
- Checkpoint
- Several Combat Forms are active in the Rally Point Bravo corridor.
- Landmark
- A Combat Form's raised weapon-side arm crossing the Assault Rifle reticle.
Do this
- 1Aim at the arm carrying the weapon first so the Combat Form stops firing while you continue farming parts.
- 2Place the Assault Rifle reticle slightly outside the hand and use controlled bursts; this reduces stray torso hits that kill the Flood before the limb separates.
Confirmation
The weapon-side arm separates before the Combat Form dies, adding a dismembered Flood part to the run.
Target
Reset the same encounter until Disarmed unlocks
- Checkpoint
- The nearby Combat Form group has been cleared and the achievement has not unlocked.
- Landmark
- The same fleshy, blue-lit Rally Point Bravo corridor with another Combat Form entering the repeatable fight.
Do this
- 1After the local enemies are gone, restart the level rather than searching deep into The Library for another group.
- 2Confirm the restart returns to Rally Point Bravo, repeat the gun-arm-first method on the same encounter, and stop when Disarmed unlocks.
Confirmation
Each reset returns to the same short approach and Combat Form group; the loop ends when the achievement or trophy notification appears.
