Soo uhh recomendation to last way longer in this mode is too hide in a blue locker of the previous room, only A-185 checks blue lockers but only in main room soo yeah blue lockers of previous room here are op!!
Ray i give you some guide about G-222 G-222: hes is very quiet and no screenshake no spawn sound rely on his audio cause sound like car from real life he will spawn his clone his clone can check locker but it slower
Hardcore mode more like chaos mode actually i thought of a custom mode Nightmare basically very removed every scrapped and old varlits can spawn from other sections and numbers
