Eric Lin has released a 14 level demo from his upcoming add-on 'Bones Alert v13.95'. The levels are on episodes 1 and 2 and are mostly very complicated levels with lots of secrets while some are fun levels. Among the contributors are ack and Dr. Chainsaw. There are some minor graphics and code changes but the main aim is to keep the original Wolf3D atmosphere intact. Text file included. Available from http://www.brlowe.co.uk/balert1395.zip . Episodes 3 thru 6 have been blanked out for copyright reasons.
