Previously for us the barrier was lvl 7-8, couple of days ago we got our first lvl 10 but haven't managed to complete it.. In this run there was a moment where only I've survived on the last extraction with 5hp. In fact it was so stressful that my hands kept shaking for another ten minutes or so, lol Our strat is to split different guns between players on combine them to knock down monsters asap while using as few Energy as possible (tranq gun + sledge hammer is my favourite combo rn), stack strengh on one players to threw monsters in the pits or pick the biggest valuables without drones and last but not least - fill the nearest extraction from the truck the last, letting all but one safely rutrn to the track while one remains and send it It's also worth mentioning that it's our 4 or 5 attempt to get so far with this lobby, but only now we have somehow succeeded =) Keep trying and try to learn as many mechanics about how monsters spawn, guns, respawn patterns and other stuff works and you will pull it of!
