Every secret, in story order

MISSABLEGundam Mk-III (for Four Murasame)
Route
Ra Cailum route (stage 1 choice)
When
Stage 4 "The Worst Ending" → unit arrives in stage 20 · Stage 4 in the walkthrough
How
Let Chan Agi shoot down Quess Paraya (Alpha Azieru) while Hathaway is still on the map. Hathaway then shoots Chan down in a story event, and that event is what the game remembers. In stage 20 Four Murasame arrives in the Gundam Mk-III instead of a Jegan, and the Mk-III stays with her.
Script
Quess’s defeat event checks who shot her down. Only the Chan branch, with Hathaway on the map, sets the Mk-III flag. Stages 20, 23 and 31 then add the Mk-III or a Jegan depending on that flag.
Old guides: The old guide also tells you to keep Char alive. The script does not check Char at all.
⏳ Missable
MISSABLEMass Production ν Gundam (Incom) + (Fin Funnels)
Route
Ra Cailum route (stage 1 choice)
When
Join for good in stage 31 · Stage 31 in the walkthrough
How
Take the Ra Cailum route after stage 1. When the future group comes back in stage 31, both Mass Production ν Gundams join.
Script
Stage 31 adds both units only if you picked the Ra Cailum route. It does not look at your stage 2 result. Stopping Fifth Luna in stage 2 (Ra Cailum at the point within 7 turns) only decides whether Kayra flies the Incom version in stages 3 and 4.
Old guides: The old guide says you must clear stage 2 within 7 turns. The script does not check it for the permanent join (not yet confirmed in a play test).
⏳ Missable
MISSABLEBlack Sarena (High Mobility)
Route
Nadesico B route (stage 1 choice)
When
Stage 31 · Stage 31 in the walkthrough
How
Take the Nadesico B route after stage 1. In stage 31 Akito comes back with the High Mobility Black Sarena. On the Ra Cailum route he gets the normal Black Sarena.
Script
Stage 31 adds the High Mobility version on the Nadesico B route and the normal one on the Ra Cailum route.
⏳ Missable
MISSABLEFebral
Route
Colony Drop route (stage 21 choice)
When
End of stage 22 "Haman's Dark Shadow" · Stage 22 in the walkthrough
How
Jamil Neate must have 20 or more kills when stage 22 ends. Jamil starts in the Freeden, so give him finishing blows from the start of the game. The Febral joins right after the map.
Script
The end of stage 22 checks Jamil’s kill count (20 or more) and adds the Febral. Stage 22 is the only place the check happens, and only on the Colony Drop route.
Old guides: Same as the old guide, but note that the Vega Rescue route has no check at all.
⏳ Missable
MISSABLEElpeo Ple + Qubeley Mk-II
Route
Colony Drop route
When
Stage 22 "Haman's Dark Shadow" · Stage 22 in the walkthrough
How
Bring Judau next to Ple and use Convince. The first attempt fails (she attacks him anyway); the second one works and Ple switches sides with her Qubeley Mk-II. Don’t let Judau attack Ple: a battle between them removes the Convince option for good.
Script
Judau gets two Convince entries for Ple. The second one runs the success scene, sets the Ple flag and moves her to your side. An after-battle event between Judau and Ple deletes both entries. She is in the roster for stage 31 and later only if that flag is set.
⏳ Missable
AUTOMATIC / NOT MISSABLEChang Wufei + Altron Custom
Route
Both routes
When
Joins after stage 23 · Stage 23 in the walkthrough
How
Nothing to do: Wufei and the Altron join after stage 23 on both routes. On the Colony Drop route you can make him change sides during the map: fight him with Heero, then use Heero’s Convince.
Script
The end of stage 23 adds Wufei and the Altron Custom without any condition, on both the Vega Rescue and the Colony Drop scenario.
Old guides: The old guide lists Wufei as a secret that needs Convince. He is not missable.
✓ Can’t be missed
MISSABLEMaster Asia + Master Gundam
Route
Both routes
When
Stages 26-27 → joins in stage 28 · Stage 26 in the walkthrough
How
Two steps. Stage 26: destroy Master Asia’s evolved Devil Gundam. If it only retreats, he is gone. Stage 27: after Emperor Gore’s first form is beaten, let Shin Getter-1’s HP fall to 30% or less. The Getter awakens and its Getter Rays clean Master Asia’s DG Cells. He joins before stage 28 with the Master Gundam.
Script
Stage 26 sets a flag only in the “destroyed” event (the retreat event does not). Stage 27 sets the awakening flag when Go’s HP drops to 30% after Gore’s first form; the cure scene needs both flags.
Old guides: The old guide only mentions stage 26. Without the stage 27 Getter event he dies in the next scene.
⏳ Missable
MISSABLEPle Two + Qubeley Mk-II (red)
Route
Space route (stage 28 choice)
When
Stage 29 "I Can See the Moon!" → unit in stage 30 · Stage 29 in the walkthrough
How
Make Ple Two talk in battle twice: Judau vs Ple Two, or Ple vs Ple Two if you recruited Ple. After the second talk Judau can Convince her and she joins on the spot. Her own Qubeley Mk-II is waiting before stage 30.
Script
Each of those battle talks adds 1 to a counter; at 2 Judau’s Convince is enabled. Glemy is not part of the check.
Old guides: The old guide says to do it after defeating Glemy. That isn’t needed.
⏳ Missable
MISSABLELancerow Dawell + Crouda
Route
Space route
When
Stages 29 and 30 · Stage 29 in the walkthrough
How
Stage 29: let Jamil fight Lancerow. Stage 30: fight him with Jamil again, then use Jamil’s Convince. Lancerow joins, and the Crouda after the map.
Script
The stage 29 talk sets a flag; in stage 30 Jamil’s Convince is only offered if that flag is set. The stage 22 talk between the two sets nothing.
Old guides: The old guide says you need the talks in stages 22, 29 and 30. Stage 22 is optional.
⏳ Missable
MISSABLEAlstroemeria (for Tsukumo Shiratori)
Route
Both routes
When
End of stage 31 · Stage 31 in the walkthrough
How
Tsukumo Shiratori must have 10 or more kills when stage 31 ends. He joins in stage 27, so give him kills in stages 27-31.
Script
Both stage 31 scenarios check Tsukumo’s kills (10 or more) and add the Alstroemeria.
Old guides: The old guide calls it “Astromauler” and “99” (Tsukumo’s name is written with the characters for ninety-nine).
⏳ Missable
AUTOMATIC / NOT MISSABLETiffa + G-Bits for the Double X
Route
Space route
When
After stage 31 · Stage 31 in the walkthrough
How
Automatic on the Space route: Tiffa joins Garrod after stage 31 and his Gundam gains the G-Bit attack.
Script
The Space-route stage 31 sets the G-Bit flag and adds Tiffa as Garrod’s sub pilot; the game checks that flag before giving Garrod’s unit the extra attack.
✓ Can’t be missed
AUTOMATIC / NOT MISSABLEFully upgraded Knight GEAR Ohga
Route
GEAR HQ route (stage 28 choice)
When
Stage 29 · Stage 29 in the walkthrough
How
Automatic on the GEAR HQ route: after stage 29 Hokuto rejoins and the Ohga’s stats are fully upgraded. Ginga’s Talk with Hokuto in the map is optional (it just brings him back early).
Script
The end of stage 29 upgrades the Ohga before Hokuto rejoins, whichever way the map ended.
Old guides: The old guide says you must fight Ohga with Dendoh. The upgrade does not depend on it.
✓ Can’t be missed
AUTOMATIC / NOT MISSABLEPhoenix Alae (Dendoh and Ohga)
Route
Both
When
Stage 35, or stage 36 at the latest · Stage 35 in the walkthrough
How
In stage 35, destroy Zero three times. If you don’t, it happens in stage 36 anyway, after Lalia, Despinis and Tis are defeated.
Script
Stage 36 checks whether the Phoenix scene already played in stage 35 and plays it if not.
Old guides: The old guide only gives the stage 35 method. You can’t miss it.
✓ Can’t be missed

Planning one playthrough

You can’t get everything in one run, because three routes exclude each other:

  • Stage 1: Ra Cailum (Mk-III chance, both MP ν Gundams) or Nadesico B (Black Sarena High Mobility).
  • Stage 21: Colony Drop (Ple, Febral) or Vega Rescue (nothing secret).
  • Stage 28: Space (Ple Two, Lancerow, G-Bits) or GEAR HQ (upgraded Ohga).

The run with the most secret units: Ra Cailum → any → any → Colony Drop → Space, feeding kills to Jamil early (Febral, 20 kills by stage 22) and to Tsukumo from stage 27 (Alstroemeria, 10 kills by stage 31).
