Hmm, that joke is probably more appropriate to a Doom wad than this, oh well.
The lull in difficulty changes almost instantly after that. A level full of more mantises. The problem? There are too many to just shoot down at once, so the level has a bunch of little rooms. Thus the level's name, The Crypt. Its mostly just moving back and forth between two of the doors, most of the doors lack a good shot at any of the enemies.
When I returned, this was going on. I guess there are undead. Forgot about that gimmick. This was actually pretty cool, although the problem I now had was that it seemed like I was stuck here, because there was a horde of these guys. This whole level exceeded at being creepy, because to begin with all the tombstones were moving.
Final Time: 8.5 hours
