-2 new (short) secret levels (at least I don't think I added them before)
-You can now interact with doors, switches, etc while carrying objects (because it's convenient having 3 hands sometimes)
-Gauss gun has a zoom in secondary mode
-Changes to Map 2-1
-Improved gun feel
-If you interact enough times with humans, you can make them follow you, which is probably not very useful outside of hardest difficulty
-You can carry the corpse of many enemies, for the sole reason while I was testing, a corpse blocked a vent. otherwise it's probably 99% useless.
-fixed electrogun not electrifying water consistently
-Stuff I forgot ? maybe ?
