I've been having a blast playing all of Intruder's missions. Even when not a single one is a masterpiece, imho, they are all worthy of your time, and each is greatly benefited by you having played the others from one single reason: Intruder is the master taffer at taking levels or aesthetics from the OMs and remaking them with a twist. This one, A Dire Return, Trail of Blood 2 and Return To The Lost City are where he plays this antic up the most, and they are his best FMs. It's lovely having all your memories flare up while playing something that is actually original (Intruder's descent into the Lost City is amazing, and the little section of the map that is shared with A Nights Profit is lovely), and Intruder does not only recreate and change but outright play with your expectations sometimes. I love having found this author's voice after some experience with his FMs. Highly recommended.
