I haven't updated Machine Gun in a while, and that's due to two things.
1; I've run out of pre written chapters, so whenever I need to update I have to sit there and write it and it usually takes a full day for me to get the chapter how I want it.
2; I've been way too busy to try and update. I just took my end of course tests, I'm getting ready for finals, and still doing school work everyday. If I took a full day to try and update Machine Gun then it would take away my time from school and I'm trying to keep my grades up. But don't worry, Machine Gun is not on hold, and an update is coming I assure you.
