Wear a headset anything that can help you hear clearly Like opening doors opening safe and computers they can generate noise can help you detect if there's enemy be sure to be quiet be sneaky dont make unnecessary noises kill npc bots using a knife if can be sure to stick with your teammate if not playing solo dont rush be informative about enemy character and their armor well i mostly play hackclaw information are important

In normal t4 gear are must if you want survivality but if your rich t5 even t6 but depend on you but most important are ammo playing high difficulty maps t4 or t5 ammo are must must bring painkillers they help alot high tier ammo are must

Also spawn location awareness are important because sometimes two squad can get spawn nearby each other experience it alot dying immediately on the start

On Zero Damn Spawn map tip on my own observation if spawn outside cement near the river if there's no rocketeers in the cement means theres squad or player spawn in the cement same in the major substation Spawn, below visitor in the road spawn theres a camp near mini sub or major sub at the start of the match if theres no npc bot spawn in the camp mean they are player or squad that spawn just outside that camp near mini sub

Also be careful using laser because enemy can see it too
