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 the biggest exploit I can think of in gaming would be back in the original Everquest days.
There was a goblin banker in the bottom of a dungeon.
He was friendly to most players, so he was convenient to drop gear off if you were farming the dungeon.
In Everquest, you could exchange between all the different values of currency at a bank. They were valued at 10 to one for each level larger. So trade 10 silver netted you one gold.
Well, they patched one da, and somehow they messed up this ratio on this one goblins banker. You could transfer 1 Platnum to 10 gold and then back to Platinum at 1 to 1 ratio. 10 times your money, basically as fast as you could click.
This one bug destabilized the entire EQ economy on multiple servers. It was used by so many and so much money was dumped on the market all over the place that the devs couldn’t get the money back out of the economy.
They banned a bunch of accounts that directly exploited it, but if you got the money second hand, there was no good way for them to “fix” it.
They probably should have just reset the servers, but they didn’t. The economy never did recover back to pre bug levels.
