MOVEMENT
Jumping boxes and ledges
Use Photon Claw-type attacks first.
Sword-type attacks work, but need more precise positioning.
Katana-type attacks are usually the most reliable.
Any attack with a clear forward lunge, such as Sword, Partisan, Dagger, Claw or Katana, can make the jump. Watch the demonstration ↗
COMBAT
Combat principles
Dolmolm / Dolmdarl
Hell Type/Shot with Hit, plus V502, is an efficient setup. Androids can freeze them first to lower their EVP, then use Hell.
Deldepth
When several surface at once, drop a Freeze Trap first, then set it off with a first hit that is likely to miss, so they can't use their hit invincibility to dodge the freeze.
Morfos
Turn the camera away from a Morfos before it spawns and keep it off screen to avoid most of its lasers. Double-Morfos waves can't always be blocked this way; keep the one you can't hide on screen and kill it first.
Delbiter
Learn their spawn lines first, then handle them quickly with freezing, Demon's or a high-Machine weapon. Hunters can also use Serene Swan.
Sinow Zoa / Sinow Zele
A high-Machine mechgun can kill them before they act. Turn on Advanced Effect and set Maps graphics to maximum, and the reflections on water and glass show their cloaked pounces.
Recobox / traps
Use Shot's centre lock to hit several targets at once. Power Maser goes through walls, hits ceiling traps and never misses because of a trap's swaying.
LOADOUT
Recommended equipment and alternatives
| Role | First choice | Alternatives and notes |
|---|---|---|
| Crowd control | Frozen Shooter, Twin Blaze, Freeze Trap | Androids should use traps proactively to lower risk and EVP. |
| Hell | Hell Type/Shot + Hit, Asteron Striker, Kiss of Death | A Hell S-Rank Needle is cheaper; a Hell Laser depends most on positioning. |
| Group damage | DARK METEOR or Arrest Needle with high Machine/Dark | BARANZ LAUNCHER is the second choice and needs freezing. |
| Single target / boss | Psycho Ravens with high Machine/Dark/Hit | For Olga Flow's first form, a Rianov 303SNR-5 with high Dark also works. |
| Support | Zalure S-Rank Launcher, Macho Blades | For lowering boss defence and keeping Shifta/Deband up. |
| Trap removal | Power Maser | Up to ten targets, instant hits, goes through walls and never misses. |
- Ranger: Hell Type/Shot with Hit is best; Asteron Striker has auto-targeting.
- Hunter: Asteron Striker or Kiss of Death; Ultima Reaper doesn't hit Dolms reliably enough.
- Force: Megid is the most direct and cheapest; Kiss of Death or a high-Hit Sacred Bow also work.
VARIANT NOTES
Per-map notes for all eight variants
Timestamps refer to the route videos above. These are additions and corrections to the videos, not steps you must follow.
UPPERPattern 1 · Variant 1
0:10After stepping on the middle trigger, go straight to the door position.0:35From the ramp corner, hit both Dolmolm at once with TypeSH/SHOT or Yasminkov 7000V.0:54On entering the bridge, stand right behind the Recobox and lock onto them together.1:59Only the three southern Recobox are needed; the eastern ones are optional.2:17Correction: the purple Dolmdarl and the Dolmolm are the same wave, so kill order does not affect when the Sinows appear.2:40Ignore the Recobox at first and run to the north-centre of the room to trigger the Deldepth.4:20Stand in the south-east corner for the first wave, then at the door for the second.
UPPERPattern 1 · Variant 2
0:17You can combo the first Sinow to death before the second one attacks; no freeze needed.0:39When the Dolmdarl appear, you can move to the door before shooting.2:13Drop any trap in the centre of the room so you can lock onto all four ceiling Recobox at once.5:36Turn back as soon as you reach the bottom of the ramp, and you can handle every Dolm together from the north side.- The claim that the Sinow Zoa in the two-switch room spawn early can't be reproduced reliably, so it is not part of the standard route.
UPPERPattern 2 · Variant 1
0:36Use the free Confuse Trap as a safety margin in case Hell misses.0:45Unless you use DARK FLOW, turning off the poison is usually not worth the detour.1:22The Sinow Zoa that drop in can be comboed to death before they move.2:24Step forward and handle both Dolmdarl in one Yasminkov 7000V combo.3:23The Delbiter spawn line is in the middle of the east half of the room, so you can stand closer to the door.4:27You can ignore the Recobox and lure both Sinow Zoa to the centre to freeze them together; faster but riskier.5:03Use a trap or a Recon as the centre lock point to hit two Recobox per attack.5:57Kill just one Recobox, then clear the four traps with a single Power Maser shot.
UPPERPattern 2 · Variant 2
2:27Hug the corner by the door and deal with the Delbiter before leaving.3:50Take the north and south Recobox first; the other two don't spawn Recon.5:02Standing by the door on the west side lets you handle the Delbiter directly, without Twin Blaze.5:56One Power Maser shot clears the traps.
LOWERPattern 1 · Variant 1
3:45Use the camera trick on the Morfos; no freeze needed.5:07Stand on the centre line of the east corridor, the furthest point of the Delbiter spawn, then freeze and kill them.6:50Run to the lower door and drop a Freeze Trap behind the right-hand Zoa, so the Zele joins the other two and you handle them together.
LOWERPattern 1 · Variant 2
0:24TypeSH/SHOT can hit both Morfos at once.1:27Ignore this Morfos; you usually won't get a shot off before it leaves view.4:59Use Power Maser to clear the traps.
LOWERPattern 2 · Variant 1
2:30Don't kill the Recobox first; go straight ahead to trigger and handle the Zoa.5:03Move to the door while the Sinows jump.5:35After the ramp, stand in the centre of the upper platform to cover all four enemies at once.6:01You can dodge the jump attacks in the middle of the corridor; at6:10, turning left makes the Dolmolm spawn sooner.
LOWERPattern 2 · Variant 2
0:10Keep to the centre.4:15You can wait for the Zele behind a pillar the Zoa can't reach, killing a Recobox to clear the way at the same time.5:43Yasminkov 7000V's auto-targeting and higher ATA suit this spot better.
