best solution: dont care about valuables, imagine them all as crap...
so when you die with Metal MKII or CA, dont say shit, dont get mad. its just a game.
why i love this game, it learnt me to keep calm and my nerves seem to get more and more used to annoying situations, when you do that, youll find this game even more fun.
and... just use low-tier weapons (mostly cripplers can use mauser, id do so) so you wont lose almost anything, and youll have bunch of them thanks to encounters.
