The most recent example of something awesome made in Vanilla Minecraft was Samasaurus6’s “Planetary Confinement”, which I reviewed and compared to Herobrine’s Mansion in terms of innovation. Today, Elementis was released. According to the trailer and description, it’s a Survival Games map, made in Vanilla Minecraft. That doesn’t sound impressive, until you read the description of the Imgur album, where the creators, a build team called “Forsaken Mapping” state that “All the game logic, chest resets and game mechanics are controlled by more than 200 commandblocks. The majority of that is a massive reset line that randomises the 100+ chests on the map.” That sounds pretty intense.
You can download the map from Forsaken Mapping’s website
