You are stuck in labs, and must make your way out.
Escape.
You have been stranded by your squad in the underground base established by Terragroup. Their access system has been destroyed, and it is up to you to make your way out, and escape Tarkov.
Gameplay.
The Labs Challenge is a mod that makes it so Labs is the only accessible map if you are under level 5. As a result of this, Labs has no keycard requirement. After level 5, you will unlock Woods, which will then take you to Factory, and etc. The level unlocks match the menu's map layout.
Progression.
Progression is as follows:
Labs > Woods (Lv. 5)
Woods > Factory (Lv. 10)
Factory > Reserve & Customs (Lv. 15)
Reserve & Customs > Interchange & Lighthouse (Lv. 30)
Interchange & Lighthouse > Shoreline & Streets (Lv. 45)
If you want a challenge, this is your best bet.
Thank you for checking out my mod.
(Thanks to Tipper#9827 for giving me the idea.)

If this doesn't work, please let me know. I'll run the mod through my computer and build it for proper use.
Keep in mind I made this on my phone, not my computer.
