The latest A Grabpack Test PREW-X update introduces Map 4, a much larger area filled with new puzzles, multiple energy sources, and an intense Huggy Wuggy chase. While none of the puzzles are especially difficult, Huggy constantly pursuing you makes the stage much more stressful.
If you’re stuck, here’s a complete walkthrough from start to finish.
Enter Map 4
From the game’s main menu, select Map 4.
After loading in, you’ll enter a dark facility. Most of the doors are locked, so continue forward until you find the only open entrance.
Inside, you’ll notice environmental storytelling, including notes left behind by previous test subjects. Keep following the linear path until the chase begins.
Survive the First Huggy Wuggy Chase
Not long into the level, Huggy Wuggy starts chasing you.
Don’t panic if you’re caught. The game allows you to continue after respawning, so simply make your way back and keep progressing.
While exploring, you’ll begin finding different colored energy sources used to activate various machines around the facility.
Activate the First Energy Puzzle
The first objective is to collect and use the nearby fire energy.
Once it’s activated, a new section of the facility becomes accessible.
Keep exploring until you locate another energy source, then return and use it to continue opening the route forward.
Open the Security Door
As you continue solving the energy puzzles, a shutter door will unlock.
Go through the newly opened passage to reach the next puzzle area.
You’ll also find laboratory notes mentioning successful experiments, confirming you’re moving through an abandoned testing facility.
Pull the Lever
Continue exploring until you find a large lever.
Interact with it to activate the next section of the map.
This changes the layout and opens additional paths while giving you a short opportunity to move before Huggy catches up again.
Break the Glass
Your next objective is to use a nearby light source to destroy a glass barrier.
Position the light correctly and activate it to shatter the glass, allowing access to the upper section of the map.
Reach the Second Floor
After breaking the glass, head upstairs.
You’ll discover additional rooms containing more energy puzzles.
Power each required machine as you encounter it to unlock the next area.
Although there are several different energy types, the puzzles remain straightforward—just activate the matching devices to restore power.
Complete the Final Puzzle
Near the end of the facility, you’ll encounter one last puzzle involving another energy source.
Once activated, the exit route opens.
At this point Huggy Wuggy continues chasing you, so avoid stopping for too long while solving the puzzle.
Escape the Maze Chase
The final section becomes a full chase sequence.
As you run, the path constantly changes, so stay focused and keep moving forward.
Avoid dead ends until you finally escape the pursuit.
Ride the Cable Car
After escaping Huggy, you’ll reach a cable car.
Ride it down into a much deeper section of the underground facility.
Once the ride finishes, continue forward to find an elevator.
Reach the Ending
Take the elevator to the final area.
After stepping outside, you’ll discover what appears to be a completely new location, suggesting you’ve finally escaped the underground testing facility.
This marks the end of Map 4.
Tips for Clearing Map 4
- Ignore most side areas unless they contain an energy source or puzzle objective.
- Huggy Wuggy follows you throughout much of the level, so avoid standing still.
- Activate each energy source as soon as you find it to unlock the next section.
- Pull every lever you encounter, as they usually open new paths.
- During the final chase, focus on the route ahead instead of looking back at Huggy.
With the combination of environmental puzzles, constant enemy pressure, and the dramatic cable car escape, Map 4 is easily one of the biggest and most cinematic stages added to A Grabpack Test PREW-X so far.
