R-4 Anomaly: Imperial Operation Walkthrough

By Imperial Dark Sector

ENCOUNTER 01 / 04 · Intake Processing Checkpoint

IP-CPT

How you reach this boss: Follow the initial pipe route through security droids to the room with floor fire vents, lasers and four colored terminals.

1. 01

   Assign four shape buttons

   Put a player near each terminal: GREEN CIRCLE, PURPLE TRIANGLE, BLUE SQUARE and RED HEXAGON.

2. 02

   Avoid fire and laser floor

   Step away from fire vents and marked blasts. Fire is especially dangerous compared with brief lasers.

3. 03

   Use shape controls on shields

   When IP-CPT floats up, new droids appear with shapes above them. Click MATCHING SHAPE TERMINALS until their shields drop.

4. 04

   Focus add phase correctly

   After unshielding, defeat or interrupt small adds and tank INFERNO / OVERLOAD enemies away from the button operators.

5. 05

   Save for final burn

   Around 30% the boss channels DISPROPORTIONATE INTRUSION RESPONSE, a hard damage timer. Use offensive cooldowns.

6. 06

   Watch the bugged boss floor

   If IP-CPT clips BELOW THE FLOOR on pull and a player cannot target it, consider an early group reset rather than wasting the whole fight.

Stuck here? Boss becomes untargetable for one player? Guides report a floor-clipping bug; reset early if that player cannot hit it.

ENCOUNTER 02 / 04 · Blue/orange polarity arena

Watchdog

How you reach this boss: After IP-CPT follow the unlocked interior route to the advanced security droid WATCHDOG.

1. 01

   Don't overlap opposite colors

   Players receive ORANGE or BLUE circles. Opposite colors touching cause severe group-wide damage.

2. 02

   Freeze during matched floor scan

   When the floor scan is YOUR color, DO NOT MOVE. Matching floor color movement can provoke a lethal pounce.

3. 03

   Drop missile circles safely

   Keep MISSILE red circles out of the team's space; group baiting requires everyone to move immediately afterward.

4. 04

   Feed correct Degauss balls

   During DEGAUSS colored balls fall at player locations. The tank guides the boss through balls matching the BOSS COLOR, not opposite-colored balls.

5. 05

   Intercept Polarized Beam

   If a colored BEAM ARROW targets a player, another player of that color intercepts between target and boss.

6. 06

   Kite during Stalking

   The targeted player moves away during STALKING rather than being caught by its contact damage.

Stuck here? If you die while apparently rooted, check if a movement ability fired during a MATCHED FLOOR SCAN.

Next encounter: Lord Kanoth →

ENCOUNTER 03 / 04 · Beyond three Nihrot hallway sections

Lord Kanoth

How you reach this boss: After Watchdog, clear the NIHROT HALLWAY before the boss: RIGHT ROOM CONSOLE first, then LEFT ROOM VALVE to burn the hardened vine barrier.

1. 01

   Solve the three hallway pairs

   For each NIHROT HALLWAY segment use the RIGHT-ROOM CONSOLE, then the LEFT-ROOM VALVE. The corridor has THREE left/right room pairs.

2. 02

   Stop the endless Grey Swarm

   Interrupt Grey Reapers and destroy ATTRACTORS. Nihrot that is burned away in this hallway does not regrow after a wipe.

3. 03

   Take grenades from the blue box

   Before Kanoth interact with the GLOWING BLUE BOX to access a temporary GRENADE and FIRE PROBE tool.

4. 04

   Burn FRESH NIHROT first

   Temporary grenades clear thin red fresh vines. Do not waste grenade charges on thick pink HARD ROT.

5. 05

   Use Fire Probes on Hard Rot

   FIRE PROBES detonate in a CROSS pattern to clear the hardened vine tiles. Tanks must move Kanoth off vine-covered ground.

6. 06

   Strip shield on Hulking add

   Use a GRENADE on the HULKING MONSTROSITY when it appears, then defeat the add before Kanoth's lethal channel ends.

7. 07

   React to major waves

   For SHOCKWAVE use a clear corner; for BLASTWAVE hide BEHIND THE MIDDLE APPARITION. Spread SEED OF ECHOES markers across separate tiles.

Stuck here? Hallway stuck in combat? Clear the remaining hardened Nihrot and use its valve. Grenades cannot clear the thick pink HARD ROT in the boss room.

Next encounter: Lady Dominique →

ENCOUNTER 04 / 04 · Final Mass Shadow Generator platforms

Lady Dominique

How you reach this boss: After Lord Kanoth follow the cleared upper facility path to Lady Dominique at the generator platforms.

1. 01

   Stand at the arena intersection

   Tank near the outer edge; damage players stand BEHIND Lady Dominique on a safe walkway.

2. 02

   Keep hacking droids alive

   Friendly droids hack the two LOW GENERATORS. Face Dominique AWAY from the one currently being hacked.

3. 03

   Use the recovery jetpack appropriately

   Concussive BLAST knocks players back; the temporary RECOVERY JETPACK saves one fall but has a cooldown. Aim your back toward a generator.

4. 04

   Drop Disturbance away

   The ORANGE DISTURBANCE marker should be moved to a different lower walkway away from the group.

5. 05

   Get back after forced knockback

   When the white knockback occurs return to her and damage through the SHIELD phase; don't get stuck on a lower walkway.

6. 06

   Swap tank on Shadow Slash

   In a later phase a tank swap occurs at several SHADOW SLASH stacks; assign a second tank or taunting DPS in advance.

7. 07

   Finish the late burn

   Coordinate offensive buffs after the generator phase and clear her final DPS check without crowding hazard puddles.

Stuck here? Repeated droid deaths? Face the boss away from the active hacker. Getting knocked off? Position your back toward a generator and don't rely on the jetpack being ready.
