 * Recipes - Sneak skill book From the test entrance turn right and go through the left door (the one sharing a wall with the "Hold up, Rocketeers!" poster), go through the door just on your right (the one sharing a wall with the Repconn poster), go through the hole in the wall on the right, go straight through the next hole in the wall, and the skill book is between the two fridges.
 * Three mine boxes, two ammunition boxes, and a LAER can be found on top of the building. It seems, however, that the roof can only be reached by jumping down from the cliff above, which in turn can only be reached by jumping up a small pile of rocks, just west of the Big MT West Tunnel.
