  1. After going through the arch east of the yellow key, staying towards the north side drops you down to an area with some imps and some health bonuses. There is a secret door in the north-east here (marked with a greenish texture) leading to a box of rockets and three zombiemen, and also allowing access to three areas that overlook the blue key area. (sector 507)


100% items is not achievable on this level as two armor bonuses (Things 193 and 194) are on top of an inaccessible platform.
