rex infernus cheat sheet: Map Route and Perks

Rex Infernus begins in the starting house, where Quick Revive is available and the early rounds are contained until the twins break open the main door. Once the exit portal becomes available, move into the central hub and use Nexus Forge as your navigation point.

The map is organized around a central forge with four major spokes. Each main area includes an armor wall, an Arsenal machine, and a crafting bench. Learning the clockwise route makes perk collection, Pack-a-Punch access, and emergency movement easier to manage.

Video Highlights:

  • Central hub layout and the clockwise route through the four spokes
  • Pack-a-Punch activation and the World Seed objective
  • Web Mother mechanics, grapple access, and early-round strategies
  • Dravacar riddle combinations and wonder weapon preparation

Route Tip

Use Nexus Forge as your fallback loop. Pack-a-Punch, the Wonderfizz area, gold rings, and nearby grapple points create several escape options.

Pack-a-Punch, Special Rounds, and Survival

Pack-a-Punch is locked behind a short environmental objective. Place the World Seed in the center of Nexus Forge, then shoot the skulls so they travel toward their assigned chambers. Collect the Essence they leave behind and continue damaging each skull until its chamber brazier ignites.

Carry the fire from each brazier back to the center and light the central brazier twice. After both fires are returned, crank the two wheels to unlock Pack-a-Punch.

The map’s special round features spiders with slowing web attacks and leap attacks. Their abdomen is the weak spot, and Dead Wire is especially useful against them. Arachnophobia mode is available for players who want to reduce the visual impact of the spider enemies.

The Web Mother begins appearing around Round 16. It can teleport, place slowing webs across the floor, cover doors and perk machines, and cocoon zombies. Destroy the webs before relying on a blocked machine or doorway. The creature’s skull is the weak spot, while Shadow Rift and Light damage are effective options.

The Titan trap is another useful defensive tool. It appears near the Vtharian and Ctherreas entrances, costs points, and can slam zombies beneath its arms. Standing in the middle of the trap is safer than standing under the descending arms.

Web Mother Warning

Do not commit to a narrow route while webs cover doors or perk machines. Clear the obstruction first, then reposition through the central hub or use a grapple.

Dravacar Riddles and Shard Puzzle

The Dravacar temple contains three outer switches, a central pillar, and a blue riddle text on the back wall. The left, back, and right switches rotate different pairs of pillars. Once the symbols match the riddle, press the central switch to submit the code.

The four symbols used in the puzzle are the star or sun, runner, galaxy, and moon. The following known combinations provide a fast reference for the listed riddles.

Riddle openingLeft switchBack switchRight switch
“I drift to the runner…”321
“I drift to stars…”122
“I remember the runner…”023
“I remember galaxies…”202
Puzzle Input Rule

Submit the code only after all switch counts are entered. A failed attempt resets the pillars, so begin the next try with a clean configuration.

1

Read the Riddle

Interact with the blue text on the rear wall of Dravacar Temple. Identify which known riddle wording matches your prompt.

2

Rotate the Pillars

Use the left, back, and right switches in the order shown by the cheat sheet. Count each interaction rather than relying on the pillar animation.

3

Submit the Code

Press the central switch to lock in the arrangement. If the attempt fails, the pillars reset and the puzzle can be attempted again on a later round.

4

Open the Secret Room

A successful solution lowers the central pillar and reveals the hidden room. Use the grapple to reach the newly accessible area.

After the temple puzzle, use an explosive at the wall near the Dravacar entrance platform to reveal a shard part. PhD Flopper can help with this interaction, although a grenade also works. Carry the part to Nixara and place it on the wall holder.

Next, align the shard holders so an energy ball can travel through the intended route. The useful alignment pattern includes middle, right, left, and right positions across the listed holders. If the energy ball stops at a dead end, inspect the last crystal in the sequence and adjust its direction with the grapple.

To create the required purple flame, grapple a purple ball and drag it toward the Pack-a-Punch area. Crank the Pack-a-Punch wheel so the fire changes color, then carry the purple flame into the temple and shoot it at the large eye. The crystal sequence begins immediately, so move quickly and aim directly at the eye.

Grappling Hook and Wonder Weapon

The grappling hook becomes available after Pack-a-Punch is opened. Interact with green fountains around the map to gain temporary grapple charges. Charges are limited per player during a round, and the fountains reactivate on the next round. In co-op, one player may still have charges after another player has used theirs.

The grapple is more than a movement tool. It can reach puzzle holders, pull purple balls, interact with dig spots, and provide emergency mobility during high-pressure rounds.

To reach the wonder weapon, enter the forest through the heart objective. Inside the forest, locate three charred bodies and collect their parts. The first part requires meleeing floorboards near a corpse inside a broken building. The second and third parts appear after interacting with their respective bodies.

The heart may require a later round before it can be eaten; Round 8 or later is the reported threshold to test if the interaction is unavailable. If the timer expires before all parts are collected, return on a later round and use the heart again.

Return routeUse the portal or wait for the return effectBrings the parts back to the map

With all three parts collected, grapple into Dravacar’s opened area and build the weapon at the bench. Its left and right sides operate independently. After Pack-a-Punching it, the weapon gains a charged fiery tornado. Charge one side while firing the other to chain tornado attacks, but monitor ammunition because the sequence consumes ammo quickly.

Wonder Weapon Tip

Charge both sides before entering a crowded area. Fire one tornado, then use the second side while the first effect ends and begins charging again.

Side Easter Eggs, Free Rewards, and Checklist

Rex Infernus includes several optional activities that reward careful exploration. The music Easter egg uses three interactions: one on a pillar in the Nixara main chamber, one on a ledge in Ruinous Insula, and one skull near the Widow’s Wine machine.

The map also contains free power-ups. The Max Ammo is hidden behind a painting in the starting house. Bonus Points are located to the left of Stamin-Up in the distance, while the Insta-Kill pickup is behind or beneath the main Nixara chamber.

For the dance mini-game, search dig spots for a cassette, then take it to the fireplace and cassette player in Arena Insula. Interact with the player to start the activity. Performance can grant rewards such as mystery perks, an Epic Aether Tool, Pack-a-Punch crystals, or other progression items.

The forest toy box becomes available after the wonder weapon route is completed. Three mini-games can be attempted, one per round: hide-and-seek with the twins, jump rope, and collecting stuffed animals while ghosts follow you. Rewards improve as the activities are completed, and later harder versions can lead to the mask reward.

Rex Infernus Progress Checklist:

Exploration Tip

Use the grapple on dig spots whenever possible. Pulling a purple ball into a dig spot can improve the quality of the resulting reward.

Q: What is the fastest way to unlock Pack-a-Punch in Rex Infernus?

Reach Nexus Forge, place the World Seed, guide both skulls to their chambers, return both fires to the central brazier, and crank both wheels.

Q: When does the Web Mother appear?

The Web Mother is associated with Round 16. Prepare by saving ammunition, learning escape routes, and clearing webs from important doors and machines.

Q: How do I get the grappling hook?

Open Pack-a-Punch, then interact with one of the green fountains around the map. Charges are limited per player during a round and return on later rounds.

Q: What should I do if the forest heart cannot be eaten?

Advance to a later round and try again. The interaction is reported to become available around Round 8 or later.
