1. I was having fun as a skulk in ns_nancy, running around in the maps rich and beautifull vent network. Then all of a sudden a marine, without jetpack I'm sure, walking around at ceiling-level (not quite the highest level of the vent, but above groundlevel for most locations on the map.) He was parasited, so I was able to kill him before he even noticed me. BUT I wonder, how the hell did he get up there?
2. At ns_bast it's possible to bust the vent outside the marine spawn. In several games I've welded it shut but later on there were fades coming in through that vent - I hate it when that happens. So how is it done? Just hitting it alot with any weapon? Is it a bug?
3. Sometimes at ns_hera the vents won't shut after welding them. At some vents you can 'use' to open & close, but I'm talking about the ones you can't use. For example, the one at holoroom, when you come from Hera Entrance & Reception and it's on the left hand side, the vent opening is shaped like a box.
