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
In Return to Castle Wolfenstein, if you save a very large non-patternic integer (1759437) and then load it, it would take a very long time to load, which in turn makes enemy encounters funny because AI will die. You will see the enemy’s hidden loadout, enemies will fall asleep on the ground, will look around but don’t shoot, etc.
You can kill them and then save. However, events won’t happen. For example, if a boos should appear, if won’t until you quicksave, exit to main menu, and then load the quicksave.
