My favorite rust moment was when me and a comrade were out roaming. He spots a base littered with Nazi paintings. I get kinda excited and immediately 180 degree turn to base to start grabbing all of our explosives. As I'm rolling up, my comrade asks, "hey what's a fashy number?". I immediately respond, uhh, "1488"? I hear the 4 beeps followed by the door unlock sound. We were able to take over their entire base without a single explosive on the very first combo we tried.
Stole their shit and converted the base to a gulag (put prison cells up around their bodies/sleeping bags). And of course replaced their signage.
