Secret Weapon Candidates¶

This document lists weapons that are not unlocked through the standard quest progression, making them candidates for "Secret Weapons" or unfinished content.

Methodology¶

1. Full Weapon List: Derived from docs/weapon-id-map.md (1-based ids 1-53; id 0 is the dummy/none entry).
2. Quest Unlocks: Analyzed quest_database_init (FUN_00439230) in crimsonland.exe.
3. Each quest entry is initialized via FUN_00430a20.
4. quest_unlock_weapon_id is at offset 0x24 (set by *(undefined4 *)(quest_meta_cursor + 0x24) = ...).
5. FUN_00430a20 sets the tier, index, and name; it does not set unlock IDs.
6. The unlock IDs are set after the FUN_00430a20 call in quest_database_init.
7. Many quests store 0 in the unlock slot; with the 1-based ID scheme, 0 maps to the dummy entry (no weapon).

Unlock Array Analysis (from quest_database_init tail)¶

The decompilation shows a series of assignments starting around line 27063. Structure: quest_unlock_weapon_id is at 0x00484754. The stride is 0x2c. So quest_unlock_weapon_id for quest i is at 0x00484754 + i * 0x2c.

The "flat" assignments at the end of the function target addresses that line up with this stride: - quest_unlock_weapon_id = 0x00484754 (quest 0 unlock slot) - DAT_00484780 = 0x00484754 + 0x2c = 0x00484780 - _DAT_004847ac = 0x00484780 + 0x2c = 0x004847ac

Quest Unlock List (weapon_id values are 1-based)¶

Unlocked List (Summary)¶

2, 3, 8, 5, 6, 12, 9, 21, 7, 4, 11, 10, 13, 15, 18, 20, 19, 14, 17, 22, 23, 31, 30, 28.

Always Available? (Checking weapon_refresh_available)¶

weapon_refresh_available clears the availability flags and then sets entry 1 available before it processes the unlock list: - Entry 0 is the dummy/none weapon. - Entry 1 is Pistol, so Pistol is always available. - In _config_game_mode == 1, it also sets entry 2 (Assault Rifle), entry 3 (Shotgun), and entry 5 (Submachine Gun) available.

This means quest_unlock_weapon_id = 0 is effectively "no weapon unlock", and some basic weapons can be available even if they never appear in the unlock array.

Missing Named Weapons (not in quest_unlock_weapon_id)¶

Named weapon IDs that do not appear in the quest unlock list:

• 1 (Pistol) - default available (see above)
• 16 (HR Flamer)
• 24 (Shrinkifier 5k)
• 25 (Blade Gun)
• 26 (Spider Plasma)
• 27 (Evil Scythe)
• 29 (Splitter Gun)
• 32 (Flameburst)
• 33 (RayGun)
• 41 (Plague Sphreader Gun)
• 42 (Bubblegun)
• 43 (Rainbow Gun)
• 44 (Grim Weapon)
• 45 (Fire bullets)
• 50 (Transmutator)
• 51 (Blaster R-300)
• 52 (Lighting Rifle)
• 53 (Nuke Launcher)

Unknown/unlabelled ranges (no names in weapon_table_init): 34-40 and 46-49.

Candidate List (Detailed Stats)¶

The following named weapons are absent from the standard quest unlock sequence (excluding default Pistol). Stats derived from weapon_table analysis:

Observations: - Weapons 41-53 often have missing or reused SFX ids (_DAT_...) and odd stats. - "Plague Sphreader" does 0 damage and likely relies on the Plague mechanic (see Plaguebearer perk). - "Fire bullets" is a named weapon entry with projectile type 60 and low damage scale; likely a bonus/test entry.

Start Weapon Analysis¶

Check quest_start_weapon_id (offset 0x28) assignments in quest_database_init. - s_Land_Hostile: *(undefined4 *)(quest_meta_cursor + 0x28) = 1; -> Pistol (1). - s_Minor_Alien_Breach: ... = 1; - ... many 1s. - s_Survival_Of_The_Fastest: ... = 5; (Submachine Gun) - Other distinct values: 6 (Gauss Gun), 0xb (Plasma Minigun), 0x12 (Rocket Minigun).

This suggests Pistol (1) is the default start weapon, with a few quests forcing specific weapons.

Conclusion for Candidates¶

Weapons not present in the quest unlock table (excluding default Pistol) are:

• HR Flamer (16)
• Shrinkifier 5k (24)
• Blade Gun (25)
• Spider Plasma (26)
• Evil Scythe (27)
• Splitter Gun (29)
• Flameburst (32)
• RayGun (33)
• Plague Sphreader Gun (41)
• Bubblegun (42)
• Rainbow Gun (43)
• Grim Weapon (44)
• Fire bullets (45)
• Transmutator (50)
• Blaster R-300 (51)
• Lighting Rifle (52)
• Nuke Launcher (53)

The late-ID block (RayGun and 41+, plus 50+) still looks like the strongest "secret/debug weapon" cluster. The midrange misses (HR Flamer, Shrinkifier, Splitter, Flameburst, Fire bullets) may be normal weapons unlocked via other mechanisms and need confirmation.
