Sync is a neat mod that clones your player and gives you the ability to play separate lives within the same world. Each clone is capable of having their own inventory, buffs, and even gamemodes. The Shell constructor is the main cloning device that runs on “piggawatts” generated by placing a pig on a treadmill near the constructor.
You can have multiple clones of yourself and select them based on your needs. The storage units can be placed anywhere and can be accessed from anywhere, which makes it somewhat of a complicated teleporter.
