Tame the Dragon โ€” Unlock Pack-a-Punch

Rounds 1โ€“5
๐Ÿ’ก
Unlike other maps Pack-a-Punch is not accessible until you ride the dragon. This must be done early. Open the streets by spending points on doors, then locate the dragon nest platform.
STEP 01
Activate the 3 generators to restore power to the city
Three generators are scattered across the open streets of Stalingrad. Each generator requires holding the interact button for 5 seconds while zombies attack. Activating all three powers the dragon nest platform and the pack-a-punch gateway.
Unlock Dragon
  • Generator 1: Near spawn, at the foot of the main staircase leading to the square.
  • Generator 2: In the central plaza area, next to a crashed Soviet tank.
  • Generator 3: In the far end of the map near the supply depot building.
STEP 02
Ride the dragon to unlock Pack-a-Punch
After generators are powered, a dragon lands on the nest platform in the central area. All players must stand on the platform and interact with the dragon simultaneously. The dragon flies to the Pack-a-Punch room โ€” the PaP machine is now accessible from the central platform.
Unlock PaP All Players
STEP 03
Pack-a-Punch your primary weapon (Tier 2 minimum)
The PaP room is in the upper tower accessible via the dragon ride. You can also return at any time by riding the dragon again. PaP Tier 2 is strongly recommended before tackling the terminal codes.

Build: Gauntlet of Siegfried

Wonder Weapon
STEP 04
Collect Dragon Scales โ€” kill dragon-touched zombies
Dragon-touched zombies (they have glowing red eyes and have been set ablaze by dragon fire) drop a Dragon Scale when killed. You need 3 scales total. Kite large zombie groups under the dragon flight paths to maximise dragon-touched kills.
WW Part 1
STEP 05
Find the Knight's Crest โ€” in the supply depot
The Knight's Crest is a metal emblem found on a shelf in the supply depot building (far end of the map). It glows faintly when approached. Picking it up is straightforward โ€” no kill requirement.
WW Part 2
STEP 06
Incubate the Dragon Egg at the nest
Find a Dragon Egg near the dragon's nest (a small glowing egg on a stone ledge). Pick it up and carry it to the incubation chamber in the lower tunnel section. Place it on the pedestal and survive 2 rounds โ€” the egg hatches into a baby dragon, which becomes the Gauntlet's companion.
WW Part 3
STEP 07
Build the Gauntlet of Siegfried at a workbench
Bring all three parts to the workbench in the armory building (mid-map, near the central plaza). The Gauntlet fires a powerful electric bolt and its alt-fire commands the baby dragon companion to breathe fire.

Complete the 4 Dragon Head Terminals

Mid-Game

Four dragon-head control terminals are positioned across the map. Each must be activated by solving a hacking puzzle while surviving zombie waves. The Gauntlet of Siegfried is required to activate each terminal.

STEP 08
Activate Terminal 1 โ€” Central Plaza dragon head
Fire the Gauntlet at the dragon head statue in the central plaza. A hacking interface opens โ€” match the sequence shown on the terminal screen within 30 seconds. Valkyrie drone spawns increase during this step.
Terminal 1
STEP 09
Activate Terminal 2 โ€” Supply Depot dragon head
The second dragon head is mounted above the supply depot entrance. Fire the Gauntlet and solve the terminal puzzle. The 30-second timer restarts if you fail โ€” keep trying.
Terminal 2
STEP 10
Activate Terminal 3 โ€” Church district dragon head
The third terminal is at the ruined church area (buy the 1250pt door from the central plaza). The dragon head is above the church entrance archway. Same Gauntlet activation and puzzle sequence as above.
Terminal 3
STEP 11
Activate Terminal 4 โ€” Spawn-side dragon head
The fourth dragon head is near the initial spawn area (on the exterior wall of the command building). After all four terminals are complete, a system-wide alert sounds โ€” this unlocks the Ragnarok DG-4 blueprint.
Terminal 4 โ€” Unlocks Ragnarok
๐Ÿ’ฃ

Build: Ragnarok DG-4 Grenades

Mid-Game

The Ragnarok DG-4 is a special grenade device that creates a gravity implosion, pulling zombies into it. It is required for the boss fight. Each player needs their own โ€” 3 parts per player.

STEP 12
Find Ragnarok Part 1 โ€” Power Cell
The Power Cell spawns in one of three locations: on the command building roof, in the supply depot basement, or near the dragon nest platform. It glows blue-white. Check all three if it's not at the first location.
Part 1 โ€” Random Spawn
STEP 13
Find Ragnarok Part 2 โ€” Detonation Housing
The Detonation Housing spawns near the church ruin area (on a pew or on a stone wall), in the tunnels near generator 3, or at the armory workbench area. Same blue glow as the power cell.
Part 2 โ€” Random Spawn
STEP 14
Find Ragnarok Part 3 โ€” Containment Tube
The Containment Tube spawns in the laboratory area (inside the building near terminal 4 spawn) or on the ground near the central dragon nest. It's a cylindrical glass component.
Part 3 โ€” Random Spawn
STEP 15
Build the Ragnarok DG-4 at the armory workbench
Take all 3 parts to the armory workbench. Assemble the device โ€” it can be thrown like a grenade and creates a powerful gravity well on detonation. Recharges every round. All players should have one before the boss.
Build DG-4

Sophia's Module โ€” Final Preparation

Late Game
STEP 16
Find all 3 Sophia AI terminals and activate them
Sophia is a Maxis-constructed AI housed in three separate terminal nodes across the map. Interact with each terminal to download a portion of her consciousness. Terminal locations: near the command building entrance, inside the supply depot office, and in the underground tunnel section.
3 Terminals
STEP 17
Assemble Sophia's Module in the PaP room
After interacting with all 3 terminals, ride the dragon to the PaP room. On a console near the PaP machine, a glowing cylinder appears โ€” this is Sophia's Module. Interact with it to collect it. This is the item needed to initiate the boss sequence.
Get Module
STEP 18
Charge the Overdrive using the dragon's energy
Holding Sophia's Module, stand under the dragon as it breathes fire. The module absorbs the fire energy to become "charged" โ€” indicated by it glowing bright orange. You need 3 full charge cycles (stand under three separate dragon fire blasts). The Overdrive is now ready.
Charge Module
STEP 19
Insert the charged module into the central console
Return to the central plaza and find the main Sophia console (a large pedestal with a slot on top). Insert the charged module to initiate the lockdown sequence. All players must be in position before inserting โ€” the boss fight begins immediately after.
Trigger Boss No return after this
๐Ÿ’€

Boss Fight โ€” The Dragon Queen

End Game
STEP 20
Enter the boss arena as a squad
After inserting the module, the arena activates in the central plaza area. The Dragon Queen descends โ€” a massive armored undead dragon entity. Make sure all players have the Gauntlet of Siegfried and at least one Ragnarok DG-4 before starting.
Required

The Dragon Queen

An ancient dragon corrupted by the Apothicons' influence. She cannot be harmed by conventional weapons โ€” only the Gauntlet of Siegfried's electric bolt can pierce her armor, and only the Ragnarok DG-4 can neutralize her regeneration.

1

Phase 1 โ€” Break the Armor with the Gauntlet

The Dragon Queen is fully armored. All players must fire the Gauntlet of Siegfried's primary electric shot at the glowing armor plates on her sides. Hit all 4 plates to crack the armor. Coordinate which plates each player is targeting โ€” she sweeps fire attacks across the arena continuously.

2

Phase 2 โ€” Expose and Stun with Ragnarok DG-4

When the armor breaks, she enters a rage phase โ€” moving faster and breathing fire constantly. Throw Ragnarok DG-4 grenades at her center mass to create a gravity well that stuns her. During the stun (8 seconds), all players unload the Gauntlet's alt-fire (dragon breath command) at her exposed weak point. She re-armors after the stun โ€” repeat this cycle 3 times.

3

Phase 3 โ€” Final Blast (All Gauntlets Simultaneously)

On the final stun cycle, when the Dragon Queen is at low HP, Sophia broadcasts a countdown. All 4 players must fire their Gauntlets simultaneously on her exposed core when Sophia calls out "NOW." The combined beam from 4 Gauntlets triggers the kill animation. If players don't fire in sync, the sequence resets and she regains partial HP.

๐Ÿฒ Boss Survival Tips

  • Save your Ragnarok DG-4 โ€” only throw it when at least 2 armor plates are broken, to maximize the stun window.
  • The baby dragon companion from the Gauntlet alt-fire deals significant damage during stun phases โ€” always command it in Phase 2.
  • Valkyrie drones still spawn during the boss fight โ€” designate one player to manage them so the other three focus the Queen.
  • Move constantly in a clockwise circle to avoid most fire sweeps โ€” standing still for more than 2 seconds guarantees a hit.
  • Use Widows Wine as a last resort when grabbed by fire tendrils โ€” it frees you automatically.
  • During the final Phase 3 countdown, don't pre-fire โ€” wait for Sophia's vocal cue to ensure all players synchronize.
