Wow you did a good job on the scary vibe. Throughout it I had my gun raised. Even blew one door open.
Never got a clear view of what was in there with me... But something did blow through a door.
In the end after retreating on top of the ship(which I did by blowing out the windows of a hanger and climbing on the side of the ship by jumping.) I ran to the edge of the ship and jumped off it and onto my own. After climbing inside I called in one of these
http://starmadedock.net/content/unsc-dd-366-destroyer.1335/ to blow up the ship. And just to be safe I blew up the ship I came into the sector with.
And just to make sure I had not missed anything... I flew the ship I called in into a star and escaped on a pelican.
I know it was a bit excessive... but for the purposes of RPing, I felt that's was the right call. For all I knew the flood could have been on that ship. Good thing I walked into somewhere on the ship that was possibly a quarantine ward, so now there is still the uncertainty that maybe I brought something back with me.
