Thats why i never used the chicago typewriter,handcannon,infinite RL etc i had another file with all the infinite stuff, its too easy and boring.
I just got my favourite weapons and upgraded them and then when i didn't like them, sold it for something else one of the weaker weapons.I'd always have the original bolt action rifle which is the maddest gun,usually black tail sometimes exchanged for a punisher,riot shotgun(the second one),minethrower,broken butterfly or a killer7.Since playing through the game so much i always had a ridiculous amount of money so i could just buy a gun, fully upgrade it and if i didn't want it just sell it lol.
Its just awhole more fun, even if it is still easy.
