To people who dont understand it, play the other submachine games. Those of you who have already been playing (and completing) the other games should understands this to some point with a little thinking ;)
It's not too hard to figure this level storyline out..
after you used the portal, you are so damn lucky that you end in a loop, with other words no matter where you go you always come back to where you started, and even worse is you go deeper within the loop for every task..however mr. m saw this coming and left you a note that this is a deathtrap and gives you the cordinations for freedom.. If you ignore those you will die, stuck in the loop forever, and dehydration is what you will die off first so...
Played through all of the submachine games with a friend and we got through them all without walkthrough (exept for part2, damn that one was pain in the arse for us) and we are still chocked over how he had created such a storyline. As you play through all the games you get to learn a bit more about the submachine net (in part 2 it all begins to make sense and that's when you REALLY becomes addicted)
