Upon buying a jetpack from a guy for 15k, I was sure it had unlimited uses, why wouldnt it? Well i equiped it and almost 30 minutes later, I left to go comp. Upon returning I had no jetpack. My suggestion is that jetpacks should have unlimited uses, like cloaks and pet kits. I spoke about this with Illusions and he said it wouldnt be favorable because it would be op, but would it really be op? Even once you find the crate, it costs 15k to get a key. And when you get a jetpack fuel prices are outrageous. For 100 fuel it costs 10k and that alone only lasts about 15 seconds. So with the large amount of money it costs to use a jetpack, is just a little fun flying around the map THAT OP?
Point is, Jetpacks should have unlimited uses.
Also note that finding the right crate is uncommon.
