#13 Wizard Of Grey (mc_rj4_lob) packs a lot of novel ideas into its space, but is marred by excessive blockiness and I think some invisible barriers (where you should be able to walk out of the low towers above the open-air courtyard). I was glad to be given the rocket-launcher, and enjoyed how it was completely the wrong weapon for what followed.
I got all 93 kills, but missed one of the four secrets.
