Secret weapon candidates¶

This page lists named weapons that standard quest progression never unlocks, and what the 1.9.93 executable does with them. Weapon ids are 1-based; see the weapon ID map. Player-facing summary: secret weapons.

Quest unlock table¶

quest_database_init (decomp/1.9/crimsonland/quests/quest_database_init.cpp) registers each quest through quest_meta_init_entry (decomp/1.9/crimsonland/quests/quest_meta_init_entry.cpp), which resets unlock_weapon_id = 0 and unlock_perk_id = perk_id_antiperk. The function's tail then assigns quest_meta_table[i].unlock_weapon_id for all 50 quests (quest_meta_table stride 0x2c). Quests not listed below store 0 (no weapon).

Start weapons (start_weapon_id) are Pistol for every quest except Sweep Stakes and Deja vu (6 Gauss Gun), Survival Of The Fastest (5 Submachine Gun), Spiders Inc. (11 Plasma Minigun), and Major Alien Breach (18 Rocket Minigun).

Availability (weapon_refresh_available)¶

decomp/1.9/crimsonland/weapons/weapon_refresh_available.cpp is the only code that sets weapon_table[].unlocked:

• clears all 64 flags, then marks Pistol (1) available;
• marks quest_meta_table[i].unlock_weapon_id for i < quest_unlock_index (capped at 50);
• in Survival (config_game_mode == GAME_MODE_SURVIVAL), also marks Assault Rifle (2), Shotgun (3), and Submachine Gun (5);
• in the full version, marks Splitter Gun (29) when quest_unlock_index_hardcore >= 40, i.e. after hardcore 4.10 The End of All; the demo forces quest_unlock_index_hardcore = 0;
• always clears entry 0.

Weapon drops and the Random Weapon perk go through weapon_pick_random_available (decomp/1.9/crimsonland/weapons/weapon_pick_random_available.cpp), which rolls ids 1..33 and rejects entries that are not unlocked. Ids 41+ can never come from this pool. Other grants are fixed ids: quest and demo start weapons, Rush (Assault Rifle), Typ-o-Shooter (Shotgun), the tutorial and spawn-template weapon bonuses (Submachine Gun), and the two Survival handouts.

Candidates¶

Named weapons outside the quest unlock table (Pistol excluded). Stats from decomp/1.9/crimsonland/weapons/weapon_table_init.cpp; ids 34-40 and 46-49 are unused slots.

Notes:

• Shrinkifier 5k and Blade Gun are run-scoped grants from survival_update; see Survival weapon handouts.
• Splitter Gun is the only persistent secret unlock (see the availability list above).
• Fire bullets (45) is the stats row for the Fire Bullets bonus, not an obtainable weapon: PROJECTILE_TYPE_FIRE_BULLETS is 0x2d, so projectile_spawn and projectile_update read its projectile speed and damage scale, and the bonus fire path reads its shot_cooldown and spread_heat (fire_bullets_fallback_shot_cooldown at 0x004d9040 and fire_bullets_fallback_spread_heat at 0x004d9048 are those fields).
• The remaining candidates have no acquisition path in 1.9.93.
