Every secret, in story order

MISSABLEVF-1J Valkyrie / VF-11C Full Armored Thunderbolt (for Gamlin)
Route
Neo Zeon route (prologue choice)
When
Start of "Fighting Mayor, Ace Milia!" · Fighting Mayor, Ace Milia! in the walkthrough
How
Give Gamlin Kizaki 6 or more kills by the end of The Boys Return to War. Before the next map a menu appears: choose Search for a machine Gamlin can fly. With 6-9 kills he gets Mayor Milia’s VF-1J Valkyrie. With 10 or more a second menu lets you pick the VF-1J or the VF-11C Full Armored Thunderbolt (the plain VF-11C Thunderbolt comes with it).
Script
The scenario’s opening checks Gamlin’s kills (6+, then 10+) and stores the pick in a story flag. Searching also sets a map variable: the enemy starts in a different formation and the defeat condition becomes 6 turns pass instead of 8. The unit stays with Gamlin and comes back with his group after each route split.
Old guides: Matches the old secrets guide. Note the cost: searching shortens the turn limit of the next map.
⏳ Missable
AUTOMATIC ON THIS ROUTEGundam Mk-III (Roux Louka)
Route
Jupiter route (split after "Raid! The Gishin Vega Fleet")
When
"Jupiter Mirage" · Jupiter Mirage in the walkthrough
How
Choose Go to Jupiter. Judau (ZZ Gundam) and Roux (Gundam Mk-III) fight beside you in Jupiter Mirage and join for good.
Script
They join as allied deployments in Jupiter Mirage. On the Kailasa-Giri route Judau and Roux still join when the groups meet again (Those from Another Earth), but without the Mk-III.
Old guides: Same as the old guide: the Mk-III and the ν Gundam HWS exclude each other.
✓ Automatic on its route
MISSABLEν Gundam HWS
Route
Kailasa-Giri route
When
Start of "Assault on Kailasa-Giri" · Assault on Kailasa-Giri in the walkthrough
How
Choose Join the Kailasa-Giri operation, and have Amuro at 50 or more kills when Assault on Kailasa-Giri starts (so by the end of Showdown! Mars and Marg).
Script
The opening of Assault on Kailasa-Giri checks Amuro’s kills (50 or more) and adds the HWS. On the Old Helios route the HWS comes back with Amuro in Emperor of Darkness.
Old guides: Confirmed: the threshold is 50 or more, checked at the start of the Kailasa-Giri map.
⏳ Missable
MISSABLEB.D. + Zame-Zau
Route
Both routes
When
"Sentimental, Back to Back" (third part) · Sentimental, Back to Back in the walkthrough
How
In the third part of the map, B.D. appears when 5 or fewer enemies are left. Bring him down to his retreat line before 3 turns have passed since he arrived. He then fights on your side in Those from Another Earth and joins.
Script
Two events lead to B.D.’s exit: ‘3 turns later’ and ‘B.D. defeated’. The recruit flag is only set if his HP is at or under his retreat line when the scene plays, so running out the clock does not count.
Old guides: Same as the old guides. The 3 turns count from his arrival, not from the start of the map.
⏳ Missable
MISSABLEVayeate / Mercurius
Route
Both routes
When
Start of "Commander of the Zaar Fleet" · Commander of the Zaar Fleet in the walkthrough
How
The game adds Noin’s and Hilde’s kills. 10 or more gives the Vayeate; 20 or more gives the Vayeate and the Mercurius. They arrive as units without pilots.
Script
Checked once, before Commander of the Zaar Fleet (that is, right after PLANET DANCE).
Old guides: The old guide put the check ‘before chapter 22’; it is the start of Commander of the Zaar Fleet.
⏳ Missable
MISSABLEFull Armor ZZ Gundam
Route
Both routes
When
Start of "Father and Son on the Battlefield" · Father and Son on the Battlefield in the walkthrough
How
Have Judau and Roux at 40 or more kills combined when Father and Son on the Battlefield starts (by the end of The Proud Rebel). Judau moves into the Full Armor ZZ.
Script
Checked before the map. On the Old Helios route Judau leaves after this stage and brings the FA ZZ back in Emperor of Darkness.
Old guides: The old guide only counted Judau. The script adds Judau and Roux.
⏳ Missable
MISSABLEGlacies + Fabularis (Joshua's partner)
Route
Joshua only
When
"Ice Doll Glacies" → "Spell of Life and Death" → "The Proud Rebel" · Spell of Life and Death in the walkthrough
How
1) In Ice Doll Glacies, use Talk with Joshua on Glacies. 2) In Spell of Life and Death, Talk to her again; a menu appears: choose Don’t cut the system. She fights beside you in The Proud Rebel and joins with the Fabularis after it.
Script
Step 1 sets a flag that step 2’s menu needs. Choosing ‘Don’t cut the system’ sets the partner flag, which changes Joshua’s mech upgrades, when Fortegigas forms, the last stages’ defeat conditions (Glacies must survive) and the ending.
Old guides: The old guide: ‘Chapter 26, select the second option’. That is the second step; the Talk in Ice Doll Glacies is required too. Recruiting her means your sibling does not come back.
⏳ Missable
MISSABLEVentus + Studium (Lim's partner)
Route
Lim only
When
"Winds of Fate" → "Spell of Life and Death" → "Say Goodbye to Me" · Spell of Life and Death in the walkthrough
How
1) In Winds of Fate, when the menu appears, choose Listen to him. 2) In Spell of Life and Death, at 5 or fewer enemies a second scene starts; choose Don’t cut the system. Ventus joins with the Studium at the start of The Proud Rebel.
Script
The ‘listen’ choice sets the flag the second menu needs. The partner flag then changes Lim’s upgrades, Fortegigas and the ending, like Glacies for Joshua.
⏳ Missable
MISSABLEMarg + Gaiyar / God Mars
Route
Old Helios route, then Gishin Empire route
When
4 steps, joins in "Showdown on the Rebel Planet!" · The Truth Revealed in the walkthrough
How
Use Takeru’s Talk on Marg in Tiger of the Galaxy, in The Proud Rebel and in The Truth Revealed (Old Helios route). Then defeat Marg’s God Mars in The Truth Revealed. Take the Gishin Empire route at the last split: Marg joins before Showdown on the Rebel Planet!
Script
Each Talk sets the next flag only if the previous one is set. The last flag is set when Marg is defeated in The Truth Revealed. The join itself is in the Gishin Empire route’s first scenario.
Old guides: The old guide says to kill Marg with Takeru whenever possible. The script only checks the three Talks and the defeat in The Truth Revealed, not who lands the hit.
⏳ Missable
MISSABLEKatejina Loos (Gottrlatan) + Chronicle Asher (Rig Contio)
Route
Angel Halo route
When
"Dance with Illusions" → "Angel Halo in Frenzy" · Angel Halo in Frenzy in the walkthrough
How
1) In part 2 of Dance with Illusions, don’t destroy Katejina or Chronicle: let them retreat at 20% HP, or beat Tassilo while both are on the map. 2) In part 1 of Angel Halo in Frenzy, Uso must fight Katejina and Chronicle. 3) In part 2, after Uso reaches the centre, Talk to Katejina first, then Chronicle. Both join on the next branch.
Script
Step 1 sets a flag; each battle in step 2 adds 1 to a counter (only with the flag); the Talk on Katejina adds the third point, and the Talk on Chronicle sets the join flag only when the counter is 3. Order matters.
Old guides: The old guide says to kill Tassilo first and ‘kill all enemies first’ in the second part. Neither is required: what matters is that both survive Dance with Illusions and the order of the Talks.
⏳ Missable
MISSABLEHaman Karn + Qubeley
Route
Angel Halo route
When
"Angel Halo in Frenzy" · Angel Halo in Frenzy in the walkthrough
How
When part 2 of Angel Halo in Frenzy starts, Amuro + Kamille + Char + Judau must have 400 or more kills together. Then clear part 2 with Kamille, Char and Judau on the map and alive. Haman joins with the Qubeley in Emperor of Darkness.
Script
The kill total is taken at the start of part 2. At the end it checks that Judau, Kamille and Char are still on the map. Amuro is counted but doesn’t have to be deployed in part 2.
Old guides: The old guide says none of the four may have 0 kills; the script only checks the total.
⏳ Missable
MISSABLERose + Zeelon
Route
Both last routes
When
"Emperor of Darkness" · Emperor of Darkness in the walkthrough
How
When Rose appears, move Takeru next to her and use Talk. She joins with the Zeelon on the next branch (Gishin Empire) or in The Meaning of “Ruin” (Planet Lux). Without the Talk she still joins, as a pilot only, and rides in the Cosmo Crusher.
Script
One Talk in Emperor of Darkness is all the script checks.
Old guides: The old guide says Takeru must battle Rose every time she appears. Only the Talk in this map matters.
⏳ Missable
AUTOMATIC ON THIS ROUTEDaltanious: Cannon Cubic, Flame Attack + Cross Slash, Hyperspace Energy Burst
Route
Old Helios route
When
"Klopen the Rebel" · Klopen the Rebel in the walkthrough
How
Take the Old Helios route. The three attacks are added at the start of Klopen the Rebel.
Script
Added automatically before the map.
✓ Automatic on its route
AUTOMATIC ON THIS ROUTEV2 Assault-Buster Gundam
Route
Angel Halo route
When
"Angel Halo in Frenzy" · Angel Halo in Frenzy in the walkthrough
How
Take the Angel Halo route. Uso gets the V2 Assault-Buster at the start of Angel Halo in Frenzy.
Script
Added automatically before the map.
✓ Automatic on its route
MISSABLERemove the anti-proton bomb from God Mars
Route
Old Helios route + Gishin Empire route
When
"Death Match! Final Battle on Gishin!" · Death Match! Final Battle on Gishin! in the walkthrough
How
Take the Old Helios route, then the Gishin Empire route. In part 2 of Death Match!, when Zuul’s first form is defeated, Kento, Danji and Beralios (Daltanious) must all be on the map. Zuul then doesn’t come back the usual way, and Takeru is no longer a defeat condition in the last three stages.
Script
The check runs when Zuul’s first form falls: Daltanious’s three pilots on the map and the Old Helios route flag.
Old guides: The old guides say Takeru must land the hit. The script doesn’t check who defeats Zuul.
⏳ Missable
AUTOMATIC ON THIS ROUTEReaction Warheads
Route
Planet Lux route
When
"Desperate Defense" · Desperate Defense in the walkthrough
How
Take the Planet Lux route. Before Desperate Defense every Valkyrie except the Sound Force (VF-1J, VF-11C, VF-17, VF-19S/F, VF-22S) and Battle 7 get the Reaction Warhead.
Script
Added automatically before the map.
✓ Automatic on its route
MISSABLEGavil + FBz-99G Zaubergeran
Route
Planet Lux route
When
"Nightmare Assault" → "Let Our Song Ring Across the Stars" · Let Our Song Ring Across the Stars in the walkthrough
How
1) In part 2 of Nightmare Assault, have Gamlin fight Gavil. 2) In Let Our Song Ring Across the Stars, have Gamlin fight the Gavigula. Gavil joins after the map.
Script
Each battle sets a flag; the second one only counts if the first was set.
Old guides: The old guide says Basara or Gamlin must fight Gavil every time. The script checks Gamlin, and only in these two maps.
⏳ Missable
MISSABLESivil
Route
Planet Lux route
When
"Let Our Song Ring Across the Stars" · Let Our Song Ring Across the Stars in the walkthrough
How
Have Basara fight Geperuniti, then Sivil fight Geperuniti, and keep Sivil alive. She joins after the map.
Script
Both battles add to a counter; the join flag is set when the count is 2 and Sivil is still on the map.
Old guides: The old guide only says to take the Macross 7 route. The two battles are required.
⏳ Missable

Planning one playthrough

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

  • Prologue: only the space route (Neo Zeon) has Gamlin’s Valkyrie check.
  • Second split: Jupiter (Gundam Mk-III) or Kailasa-Giri (ν Gundam HWS).
  • Third split: Old Helios (Marg, bomb removal, Daltanious attacks) or Angel Halo (Haman, Katejina & Chronicle, V2 Assault-Buster).
  • Final split: Gishin Empire (Marg, bomb removal) or Planet Lux (Gavil, Sivil, Reaction Warheads).
  • Hero: Joshua can recruit Glacies, Lim can recruit Ventus.

The two strongest combinations: Old Helios → Gishin Empire (Marg plus a bomb-free God Mars) or Angel Halo → Planet Lux (Haman, Katejina, Chronicle, Gavil and Sivil). Rose, B.D., the Vayeate/Mercurius and the Full Armor ZZ are available on every route.
