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
NHL 2001 you could flip the puck in the zone on net from anywhere outside the blue line and goalies would just flip and miss it every time. Exploited this against my little brother for a few games until every game was in the high 20’s low 30s.
