I just saw a glitch that turned out to be a feature. The collectible items icons where visible from much farther that usual and the range of the minimap was larger. I liked it so much!, but it only happened for the military base I was at the moment...
I'm going for 100% completion and sometimes it's very boring to have to sweep an area on foot just to find a missing package/small destructible.
Is there any mod that could make the life easier with this? I couldn't find anything at http://www.justcause2mods.com/
