A mod about exploiting the game, from inside the game.
From time-to Time, you may glitch cores in your world.
This represents where the code has failed, and has created the foothold for an exploit.
Unfortunately, you can't remove the glitch itself, but with the Glitch Harvester, you can collect some information about the crash. And use an analyzer to search for possible exploits. Sometimes, you will get a good exploit. Sometimes, you just get a mess of code. And other time, nothing!
There are a number of exploits available, but most of the only make sense on multiplayer servers.
Learning about them is half of the fun! The shards are pretty pointless... maybe there is a use for them.
