Halloween The Game Prologue Challenge 5 No Alerts Guide

This guide explains how to complete Challenge 5 in the Halloween The Game prologue without triggering any alerts, which is required to earn the associated achievement. You need to move through the level while avoiding enemy detection, and the key is to use stealth takedowns and time your movements carefully. Below is a step-by-step route, along with tips for handling the patrol patterns and environmental hazards.

Formula

The calculator above works out your average pace and speed for a given distance and time. The formulas are:

• Average pace = Finish time (minutes) ÷ Distance (kilometers), giving minutes per kilometer.
• Average speed = Distance (kilometers) ÷ (Finish time (minutes) ÷ 60), giving kilometers per hour.

Variables: t = total time in minutes, d = distance in kilometers. Pace is expressed as min/km, speed as km/h.

Worked Example

Using the default values (50 minutes, 10 km):

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows 5.00 min/km and 12.00 km/h.

Understanding the Challenge

Challenge 5 in the prologue is a stealth mission where the goal is to reach the exit without being spotted by any enemy. The “no alerts” condition means you cannot trigger a chase or combat state. This is different from simply not dying—if an enemy sees you and starts chasing, the alert triggers even if you escape. The game tracks this internally, and the achievement will not pop if any enemy becomes aware of your presence.

The level is set in a small outdoor area with a few buildings, fences, and patrolling enemies. There are typically three to four guards, each with a set patrol route. Some stand still, others walk back and forth. You must use cover, crouch, and time your movements to avoid their line of sight. The game gives you a flashlight that can be toggled, but it does not affect enemy detection—only your visibility to the player.

Step-by-Step Route

Here is a reliable path that works on normal difficulty. You can adjust if your game version differs slightly, but the layout is consistent.

1. Start – You begin behind a low wall. Crouch immediately and wait for the first guard (patrolling left to right) to pass. He walks a loop around the central shed.
2. Move to the first bush – When the guard turns away, sprint to the bush near the left side of the map. Crouch and wait.
3. Wait for the second guard – A stationary guard stands near the far left corner, facing the path. He only turns around occasionally. Wait until he faces away, then move to the shadow of the large tree.
4. Cross the open area – The third guard patrols between the two buildings. Time your crossing when he is behind the right building. Use the dumpster as cover.
5. Enter the first building – The door is unlocked. Inside, there is a window overlooking the courtyard. No enemies inside, but stay crouched to avoid being seen through the window by the patrolling guard.
6. Exit through the back door – The back door leads to a narrow alley. The fourth guard stands at the end, facing away. Sneak up and perform a silent takedown (press the interact key when prompted). This does not trigger an alert.
7. Final stretch – After the takedown, the exit gate is directly ahead. Open it and walk through to finish.

If you miss a takedown or are spotted, reload the last checkpoint (the game auto-saves at the start) and try again. The entire run takes about 3–4 minutes once you know the route.

Common Mistakes and How to Avoid Them

Many players fail the no-alert condition due to small errors. Here are the most frequent ones:

• Running in the open – Always crouch when moving between cover. Running creates noise and makes you easier to spot, even at a distance.
• Not waiting for the full patrol cycle – Guards have a set path. If you move too early, you might bump into them. Watch for one full cycle before moving.
• Using the flashlight – The flashlight does not affect enemies, but it can make you think you are hidden when you are not. It is safe to leave it on, but it does not help.
• Takedown timing – When performing a takedown, you must be behind the enemy and close enough. If you are too far, the prompt does not appear, and the enemy may turn around. Wait until the prompt shows.
• Forgetting about the window – Inside the first building, the window faces the courtyard. If you stand up, the patrolling guard outside can see you. Stay crouched until you leave.

Comparing to Other Challenges

Challenge 5 is the only one in the prologue that requires a completely clean run. Earlier challenges allow combat or have different objectives (like collecting items or reaching a point within a time limit). Challenge 5 is more about patience than skill. The enemies are slow and predictable, but the map is small, so there is little room for error. Compared to later challenges in the full game, this one is considered easy once you memorize the patrol routes.

Some players confuse “no alerts” with “no kills.” You can kill enemies silently without triggering an alert. The only thing that matters is whether an enemy sees you and raises an alarm. A silent takedown is safe. If you prefer, you can also avoid all enemies entirely—the route above uses one takedown, but you can skip it by waiting for the stationary guard to turn and then sprinting past him to the exit. That is riskier because he might turn at the wrong moment.

Costs and Rewards

There is no in-game currency or purchase involved. Completing Challenge 5 with no alerts unlocks an achievement/trophy (name varies by platform). It also unlocks a cosmetic item or a bonus for the full game, depending on your platform. The prologue itself is free, so there is no financial cost. The only “cost” is your time and patience. If you fail, you simply reload the checkpoint—no penalty other than lost progress.

Safety and Fair Play

This guide is for legitimate gameplay. Do not use third-party cheats or mods to bypass the alert system, as that may corrupt your save or get you banned from online features (if any). The game is single-player, but some platforms have anti-cheat for achievements. Stick to the intended mechanics. Also, note that the game has a horror theme with jump scares; if you are sensitive to that, play with headphones at a low volume.

Frequently Asked Questions

Q: Do I have to kill all enemies to get no alerts?
A: No. You only need to avoid being detected. You can sneak past everyone, or silently take down some. Killing is not required, and killing loudly (e.g., with a gun) will alert everyone.

Q: What happens if I get spotted but escape?
A: The alert is triggered the moment an enemy starts chasing you. Even if you lose them, the achievement will not unlock. You must reload the checkpoint.

Q: Is there a time limit for this challenge?
A: No. You can take as long as you want. The only condition is no alerts. Patience is your friend.

Q: Can I use the environment to distract enemies?
A: In the prologue, there are no throwable objects. You can only rely on timing and cover. Some players report that opening doors creates noise, but it does not consistently attract guards.

Q: Why does the guard sometimes see me through the window?
A: The window in the first building is transparent. If you stand up or move too close, the patrolling guard outside can see you. Stay crouched and keep to the back wall.

Q: What if I miss the takedown prompt?
A: If you are too far, the prompt will not appear. Move closer until the prompt shows, then press the key. If the enemy turns, back off and try again from a different angle.
