I don't do videos unfortunately. I just play and talk about trickery on the forums. If you hadn't noticed, I made a couple posts regarding fun on The Silent Cartographer. The links are here:

Marine Blasting on The Silent Cartographer
Marine Trapping on The Silent Cartographer

I think those are pretty cool things to find, though they both involve the sadistic torturing of Marines, which may bother some people. I also helped spur Rockslider's interest in the Cavern Megabattle, though he was the one who took the extra step and added in the enemies from the Two-Wraith area, which, I have to say, makes that megabattle so much more, well, mega (my version just involved condensing the enemies already present in the cavern area). I've only tried it on Easy, but I will probably try it out on Normal pretty soon.

Vale,
