System Shock 2 -
When you're ready for some backtracking head for the tram and go to the umbilical, shown on the map above. Oh surprise, we can't leave yet as Korenchkin blocks the way with a force-field. He asks me to meet him on the command deck to talk. Since that doesn't sound like a trap -at all- I eagerly accept! As I leave I take a med kit, an anti-toxin hypo and 12 armor piercing bullets from the body.
