Blackhawk Rescue Mission 5 Gas Mask Overview
The customized M50 is a facewear item earned through the Zombies mission chain in Blackhawk Rescue Mission 5. It is tied to Research Fellow Part 2, an Extreme-rated mission that sends players into the Metro hospital main tower for personnel files.
The reward is more than a visual trophy. The customized M50 provides the same chemical protection as the standard M50 when a filter is available in the player’s inventory. Its main distinction is appearance: the mask can display different patterns, visor treatments, and an optional chemical hood.
Video Highlights:
- Research Fellow Part 2 takes place inside the heavily contaminated Metro hospital.
- Multiple gas mask filters are recommended for the hospital route.
- The reward is a customized M50 with several appearance options.
- The mission ends with extraction from a nearby helipad after finding the personnel files.
The standard and customized versions share the same protective behavior. The custom model is therefore best understood as a completion reward and personalization item rather than a stronger protective tier.
| Item | Role | Protection behavior | How to obtain |
|---|---|---|---|
| Standard M50 | Chemical protection | Requires a filter in inventory | General facewear option |
| Customized M50 | Reward and customization | Functions like the standard M50 | Complete Research Fellow Part 2 |
| M50 hood | Appearance add-on | Does not replace the filter requirement | Purchased through customization |
| Gas mask filter | Consumable support item | Enables chemical protection | Bring filters before entering gas zones |
Mission Reward
The customized M50 marks completion of one of the most demanding Zombies missions.
Chemical Protection
The mask protects against contaminated areas only while a suitable filter is available.
Operator Style
Patterns, visor colors, and an optional hood let players create a more distinctive operator appearance.
Treat the customized M50 as both practical facewear and a progression badge. Its value comes from the mission it represents as much as from its visual options.
Research Fellow Part 2 Walkthrough
Research Fellow Part 2 is the key mission for obtaining the customized M50. The objective is located in the Metro hospital main tower, where the HR office contains the personnel files. The route is dangerous because zombies continue to appear while you push deeper into the building.
The mission becomes more manageable when you divide it into three priorities: reach the hospital, secure the files, and extract without wasting your remaining filters.
Accept the Mission and Prepare
Select Research Fellow Part 2 and review your loadout before deployment. Bring multiple gas mask filters because the hospital area contains a high level of toxic gas. Use a weapon setup that remains comfortable in confined corridors and stairwells.
Reach the Metro Hospital
Travel to the Metro hospital main tower and begin the approach carefully. Avoid unnecessary fights outside the objective path, since ammunition, health, and time become more important once you enter the contaminated zone.
Enter the A-Wing Stairwell
After entering the hospital, locate the stairwell in the A wing. The objective requires a long climb through approximately 15 flights of stairs, with hostile zombies creating pressure along the route.
Find Room 15A3
Continue to the HR office in room 15A3. Obtain the key if required, enter the office, and search for the hospital personnel files. Keep your exit plan in mind before beginning the search.
Extract at the Helipad
Use the nearby helipad extraction point after securing the files. Call for extraction with your C-Cell, board the transport, and return to base to receive the customized M50 reward.
| Mission stage | Main objective | Primary risk | Recommended response |
|---|---|---|---|
| Deployment | Start Research Fellow Part 2 | Poor preparation | Carry several filters and a confined-space loadout |
| Hospital approach | Reach the main tower | Zombie contact | Limit unnecessary engagements |
| A-wing stairwell | Climb toward the objective | Repeated zombie spawns | Clear sections, reload, then keep moving |
| HR office | Search room 15A3 | Delayed objective completion | Secure the key and search methodically |
| Helipad | Call extraction | Running out of protection | Leave immediately after the files are secured |
Do not treat the hospital as a quick in-and-out location. Toxic gas, repeated zombie spawns, and the long stairwell can consume filters and resources before the objective is complete.
Gas Mask Filters and Survival Preparation
Filters are the most important preparation item for this mission. The contaminated hospital can drain filter durability while zombies force you to stop, fight, or reposition. Entering with only one filter leaves little flexibility if the route takes longer than expected.
The available reference material indicates that rare filters may last around ten minutes, although exact durability can vary by circumstances or game updates. Use that estimate as a planning guideline rather than a guaranteed timer.
Before Entering the Hospital:
- Carry multiple gas mask filters in your inventory
- Confirm the customized or standard M50 is equipped
- Bring enough ammunition for repeated zombie encounters
- Identify the A-wing stairwell and nearby helipad route
- Keep a C-Cell available for extraction
| Preparation item | Why it matters | Priority |
|---|---|---|
| Multiple filters | Extends operating time in toxic gas | Critical |
| Reliable primary weapon | Handles repeated zombie encounters | High |
| Spare ammunition | Prevents forced retreat during the stair climb | High |
| C-Cell | Calls extraction after the files are collected | Critical |
| Clear extraction plan | Reduces time spent inside the contaminated zone | High |
Use the following survival rhythm inside the hospital:
- Move from one defensible section to the next instead of sprinting blindly.
- Reload before entering another stairwell segment.
- Avoid spending all ammunition on distant or avoidable targets.
- Check filter condition during pauses, not only after reaching the objective.
- Once the personnel files are secured, prioritize extraction over additional exploration.
A strong team can divide responsibilities by assigning one player to lead through the stairwell, one to watch the rear, and one to manage the objective interaction. Solo players should slow down at landings and use each pause to reload and reassess.
The helipad is positioned close to the objective, so the safest finish is usually to secure the personnel files and call extraction without taking an unnecessary detour.
Customized M50 Patterns and Visor Options
After completing the mission, the customized M50 becomes a flexible appearance option. The available customization system includes five named patterns: NA, Jaws, Stalker, Tears, and Tribal. Players can also add a hood and change the visor color.
The customization does not change the mask’s chemical protection behavior. Choose options based on your operator’s visual theme, squad identity, or preferred tactical style.
| Customization group | Available options | Gameplay effect |
|---|---|---|
| Mask patterns | NA, Jaws, Stalker, Tears, Tribal | Visual change only |
| Hood | Combat vehicle protective chemical hood | Covers the wearer’s head visually |
| Visor colors | BlueBlocker, Clear, Laser, Mirrored, Sunlight, Tinted | Changes lens appearance |
| Protection | Filter-supported chemical protection | Matches the standard M50 behavior |
The reference wiki identifies the customized M50 as a facewear item with a nominal purchase cost of 10 Credits after completing Research Fellow Part 2. The mission completion requirement remains the central unlock condition, while the listed customization options are separate appearance choices.
| Option | Visual identity | Best fit |
|---|---|---|
| NA | Default presentation | Clean military or neutral outfits |
| Jaws | Aggressive markings | Combat-focused operators |
| Stalker | Darker, intimidating appearance | Night or covert-themed kits |
| Tears | Distinctive marked design | Individualized roleplay outfits |
| Tribal | Strong graphic pattern | High-contrast operator styles |
| Clear visor | Untinted lens | Minimalist or standard appearance |
| Mirrored visor | Reflective lens | High-visibility custom outfits |
For a restrained military look, pair the default NA pattern with the Clear visor. For a more recognizable character design, use Jaws, Stalker, Tears, or Tribal with a contrasting lens. The hood can help create a heavier quarantine-zone appearance, especially when combined with darker visor treatments.
For additional item details, see the M50 (custom) page on the Blackhawk Rescue Mission 5 Wiki.
The M50’s patterns and visor treatments are cosmetic choices. They do not replace filters or create a separate protection level, so preparation still determines mission performance.
Common Mistakes and FAQ
The most common failure is entering the hospital without enough filter capacity. The second is treating the stairwell as a straight sprint. Long indoor routes become much safer when players pause at natural breaks, manage ammunition, and keep the extraction objective in view.
| Mistake | Why it causes problems | Better approach |
|---|---|---|
| Bringing one filter | Toxic gas may outlast the filter | Carry multiple filters |
| Fighting every zombie | Wastes time and ammunition | Engage threats blocking progress |
| Ignoring the stairwell | The A-wing climb is a major route segment | Reload and reset at landings |
| Exploring after the objective | Adds exposure without improving the reward | Move directly to the helipad |
| Forgetting the C-Cell | Delays extraction after the files are found | Check it before deployment |
