BRAIN / OUT

83.33 hours is all you need to earn this achievement, you can idle this achievement in your safe hub area. I would prefer if you use that time to play and grind weapon kills and other free play.

All miscellaneous achievements, all are grindable and can only be earned through players not bots. Boosting would definitely help.

The four achievements are only earned through Free Play.

First, choose any mission, exit and enter Free Play again until you get Scout (My curiosity made me do this first time).

Second, buy 20 dog tags from the market inside your stash room with your converted rubles, it is very cheap unless someone did the inflation move.

Third, buy 10 medkits and enter the conflict area, then find a high place but not to kill yourself, this means you can spam medkit to heal yourself and try again until you earn the achievement.

Fourth, this one might be frustrating so you may need to do this in 2-3 days but also wait in real time (OS clock) because I got the code around 22:00 and then 00:00 in my own timezone, I'm sure if you can wait during evening or close to midnight so the code will be told on the radio (Radio Receiver on market). Then keep going right at the city location (end of the map) by the same area. Then, solve the bunker fuse after entering 4-digit code and then make sure you must crack the safe by turning the knob slowly, you will hear the click sound while the tumbler changes in highlight. Then after solving it you can exit and do this repeatedly 3 times.

Here is the step on cracking safe:

1. Turn knob counterclockwise
2. Hear the click, turn knob clockwise
3. Same but clockwise

I hope you have boosting players and people to help you. Some of the weapons could be earned from the following:

• Complete tasks
• Collect blueprints
• Do Free Play
• Level up

These will add up IF you kill only players not bots.

However, Shadow Company and Antiseptic is obtained by coop quest which had been removed since 2020.
