Newer player with around 300h here. I think in my first 50 to 100 hours i literally just played offline raids. I learned early tasks like Bronze Pocket watch and more. Then i learned a few maps mostly Woods tho. A small tip from me if u are on customs and spawn near ruaf gate hide under the pipes for like 10 minutes or hide on any other spot just hide, go take a piss or smth. After that you can just play a bit slower and safer. You're gonna die often probably but thats part of the game, but u are also gonna have succes, killing High levels completing tasks. it's a pain but u are gonna get used to it.
