F1: The Nest

Alright, so you've landed on ALT://R1B1, also known as 'F1: The Nest'. This is where things get a bit more interesting because it's our first real taste of the 'Gather Items' objective. Your main goal here isn't just to survive, but to actively hunt down 12 Personnel IDs (PIDs) scattered across the map. Don't worry, you don't have to clear every single zone, which gives you some breathing room and a chance to make smart choices about where you go.

Walkthrough

1
Objective: Your primary mission is to find and collect 12 Personnel IDs (PIDs). There are a total of 18 PIDs available across zones 39-45, so you have some flexibility.
2
Zone Options: You have a few ways to tackle this.
3
Option 1 (High Risk, High Reward): Zones 43, 44, and 45.
1. Start by entering Zone 43. This zone triggers a Class II Alarm, so be ready for a fight. Your main goal here is to grab some PIDs. Crucially, there's a Colored Key in this zone. Grab it!
4
Next, head into Zone 44, which has a tougher Class III Alarm. More PIDs to collect here.
5
Finally, push into Zone 45, another Class III Alarm zone. Collect the remaining PIDs you need.

Option 2 (Safer, but requires more exploration): Zones 41 and 42.

Enter Zone 41 and start collecting PIDs. Keep an eye out, as this zone contains a Scout.
Move into Zone 42 and continue gathering PIDs. This zone also has a Scout.

Option 3 (Dangerous, needs the key): Zones 39 and 40.

To access these zones, you'll need that Colored Key you hopefully grabbed from Zone 43.
Enter Zone 39 and collect PIDs. Be warned: these zones are packed with dangerous enemies like Giants and Big Shooters.
Proceed to Zone 40, which also has a high concentration of Giants and Big Shooters, and grab the last of your PIDs.

Extraction: Once you've secured at least 12 PIDs, make your way back to the starting point and extract.

Recommended Path: For a good balance of safety and efficiency, try this route: Zone 43 (grab the key and PIDs) > Zone 44 (more PIDs) > Zone 41 (PIDs and a Scout) > Zone 42 (PIDs and another Scout). This path usually gets you enough PIDs without needing to brave the heavily infested Zones 39 and 40, and you avoid the Class III Alarm in Zone 45.

Tips

Resource Management: Keep an eye on your ammo, health, and tools. Zone 38 has minimal resources (20% each), while most other zones offer a much healthier 40% Ammo, 60% Medi, and 40% Tool. Plan your engagements accordingly.
Enemy Awareness: Be particularly cautious in Zones 39 and 40 if you choose that path, as they are heavily populated with Giants and Big Shooters. Scouts in Zones 41 and 42 can also be a nuisance if not dealt with quickly.
Key Acquisition: Don't forget that Colored Key in Zone 43 if you plan on exploring Zones 39 and 40. It's essential for unlocking those paths.
Flexibility: Remember you don't need all 18 PIDs. Focus on efficient collection routes to minimize unnecessary risks.

B1: Data Retrieval

Alright, so you've landed in ALT://R1B1, also known as 'PID Search'. This is your first real taste of the 'Gather Items' objective, which means we've got a specific number of things to find before we can bail. The cool part? You don't have to clear every single zone. We can be a bit strategic here.

The main goal is to snag 12 Personnel IDs (PIDs). You'll find up to 3 in each of the zones from 39 to 45, so there are more than enough scattered around. We just need to pick the best path.

Here are your main options for grabbing those PIDs:

Option 1: Zones 43, 44, and 45

First up is Zone 43. Brace yourself, it's a CLASS II ALARM, so expect trouble. Grab the PIDs here.
Inside Zone 43, you might find a Colored Key. If you do, it's super useful because it unlocks the door to Zone 39.
Next, push into Zone 44. This one's a tougher CLASS III ALARM, so be ready for a fight. Keep an eye out for more PIDs.
Finally, hit Zone 45, another CLASS III ALARM. More PIDs await, but this zone can be a real pain.

Option 2: Zones 41 and 42

This route is a bit more straightforward. Head into Zone 41 and start collecting those PIDs.
Then, move on to Zone 42. You'll find more PIDs here.
Heads up: Both Zone 41 and Zone 42 have a Scout lurking around, so stay sharp.

Option 3: Zones 39 and 40 (Requires the Colored Key from Zone 43)

If you managed to snag that Colored Key from Zone 43, you can access Zone 39. Grab the PIDs inside.
Then, make your way to Zone 40 for the remaining PIDs.
Big Warning: Zones 39 and 40 are crawling with Giants and Big Shooters. These guys hit hard, so tread carefully.

Once you've collected at least 12 PIDs, just head back to where you started and hit the extraction point. Easy peasy.

Pro Tip for a Smoother Run:

If you want to make things a bit less hectic, try this path: Start with Zone 43, then move to Zone 44. After that, hit Zone 41 and then Zone 42. This way, you'll likely get enough PIDs without needing to brave the tough Zone 45 (which has a CLASS III ALARM) or deal with the heavy hitters in Zones 39 and 40. You'll still have plenty to complete the objective.
