When I was playing dying light with friend we discovered that every timw you go to sleep and wake up air drop will appear, if you don’t know air drops are pretty rare and if you collext them and deliver to one guy you will recieve lots of xp, we used that multiple times to unlock grapling hook very early. Air drops also gave lots of medicine which was hard to get in early game and that very helped us
I didn’t discover it but learned it from a friend. Cloning pokemon in gen2 (don’t remember if it worked in gen1) by turning the console of after swapping a Pokémon from a box to your party but before the game saved the changes.
