Havoc weapon system

Source: STR#7D02.dat (pickup banner text) and STR#7D03.dat (HUD active weapon names), extracted from INTRFACE.FF. True class structure and game logic to be confirmed via Ghidra decompilation of HAVOC.EXE.

Player memory: 6 weapon classes each for primary (infinite ammo) and secondary (limited ammo).

---

Primary weapons (infinite ammo)

Weapons not appearing in the pickup table are assumed to be starting/default weapons. Upgrades within a class are listed tier by tier.

Class	Tier 1 (start)	Tier 2	Tier 3	Tier 4
Laser	Laser	Improved Laser	ElectroLaser	High-Power ElectroLaser
Disc	Disc	Improved Disc	Disc Gun Doubler	High-Power Disc / Fin-Stabilized Disc
Shockwave	Shockwave	Radial Shockwave
Fireball	Fireball	High-Velocity Fireball
Plasma	Plasma	High-Energy Plasma
VARG	VARG Omicron	VARG Omicron High-Power	VARG Omicron Focused	VARG Photon / VARG Photon High-Energy

Notes:

• "Laser Doubler" pickup grants a second laser barrel (doubles fire rate/output, not a separate class).
• "Disc" and "Improved Disc" do not appear as pickups -- probably starting weapons.
• "Plasma" does not appear as a pickup -- probably starting or granted via progression.
• VARG (Variable Armament Resonance Gun?) is the highest-tier class, with two sub-branches (Omicron / Photon).

Secondary weapons (limited ammo)

Cheat code mmm gives the best Heatseeker class weapon. Cheat aaa = max ammo for all secondaries.

Class	Base weapon	Upgrade(s)	Ammo pickup
Rocket	Rocket	Rocket Repeater, Rocket Doubler	Rocket Ammo +5 / +10
Cruise Missile	Cruise Missile	Afterburner Cruise	Cruise Missile Ammo +5
Mortar	Mortar	High-Impact Mortar	Mortar Ammo +5
Mine	Mine Dropper	Thermite Mine Dropper, Proximity Mine Dropper	Mines +5
Heatseeker	Heatseeker	Afterburner Heatseeker	Heatseeker Ammo +5
EMP	EMP Cannon	Improved EMP Cannon	EMP Cannon Ammo +5
Fusion	Fusion Cannon	Catalyst-Aug Fusion Cannon	Fusion Cannon Ammo +5
LGM	Laser Guided Missile	Thermal LGM, ElectroCharge LGM	LGM Ammo +5
Warhead	Warhead	Multi-Warhead	Warhead Ammo +5
Sweep Dropper	Sweep Dropper - Laser	Sweep Dropper - Photon, Sweep Dropper - Flame	Sweep Dropper Ammo +5
Terraformer	Terraformer	Enhanced Terraformer	Terraformer Ammo +5
Phase Missile	Phase Missile	Dual-Phase Missile	Phase Missile Ammo +5
Catapult	Ion Catapult	Meson Catapult	Catapult Ammo +5
Disruptor	Disruptor Cannon	High-Phase Disruptor Cannon	Disruptor Cannon Ammo +5

Note: The data shows 14 distinct secondary weapon lines, but player memory is 6 classes. Likely some of these are grouped into the same class slot in the UI (e.g. Rocket + Cruise Missile may share one slot, LGM + Phase Missile another). Ghidra will resolve the actual slot count.

Unaccounted-in-pickups (appear only in HUD list, may be starting secondaries):

• Pulse
• Frequency-Modulated Pulse
• Particle Accelerator
• High-Velocity Particle
