During Infection, I was some how glitched below the map Hi-jacked as soon as the round was put in progress. What is below spawn is the hollowed out ship. Here are some screenshots of what was there. Where I first landed. Spoiler A look at spawn. Spoiler Some bedrock under the place where the heli-copter is at the front of the ship. Spoiler The floor of the control tower. Spoiler The boiler room. Spoiler Some signs against the outside of the boiler room. I don't know what they say, anyone else have an idea? Spoiler That was my journey underneath Hi-jacked.
I just realized it must be pretty difficult for everyone to see what it says on the signs at that size. Here's a better Picture
I wonder if any other maps have a interesting place under them, so that someone could glitch under and see.
