You are “allowed” to use whatever mods you desire in this map, although the creator recommends just playing it in vanilla Minecraft. The One-Block Survival Map poses some very interesting challenges and it is a lot of fun trying to get away and move on.
Getting to them won’t be easy though, and you will have to think outside the box (or block, hah!) to get there. In the distance you will also see several different islands which you must strive to reach, all with different purposes. Right next to you on your little block of bedrock is a island with trees, and one with mushrooms, so you have something to work with. Don’t fret though, as it should be called “One-Block”, the bedrock block is not the only thing in this world. The One-Block Survival Map for Minecraft is a pretty interesting map, in that you start out on a piece of bedrock, and from there on, must try to survive.
