Captive Minecraft 4: Winter Realm, is a vanilla-style, low difficulty version of Captive Minecraft. Or, since it is now using the new combat system, and I am doing horrible at it, it is using the very difficult new vanilla combat mechanics where even one skeleton plus one spider killed me in testing.
As Kefke calls the series: Overhyped Caverns of Doom.
As I call this map: Vertical Vanilla Viewing.
Episode 0 (intro to Captive Minecraft and the map, of interest if you've never seen Captive Minecraft):
Outtakes, derpage, silly conversations.
Everything from skyblock map ideas, to what happens when an army of Red Dragons (fire-breathing) attack a D&D party where one person has fire immunity, but everyone else is vulnerable.
Special bonus: See me use dirt turning to grass as a timer/clock :). Yes, I was watching grass grow while we were talking.
