    The Free Online Multiplayer Hacking Platform Shooter

    Welcome to CYPHER. A corrupt government controls Mars as corporations sell oxygen at a premium. You are an agent with an incredible skill set determined to eliminate the system. Taking information is how you will do it; unfortunately, other organizations are seeking what you are. They will stop at nothing to steal the valuable data you hack... The plot of CYPHER is the overthrow of the tyrannical Martian government. In the not-too-distant future, colonization of Mars has been completed and the new government is being influenced by evil corporations. These organizations are rife with corruption and greed. The populace seems to not notice or care, lulled into a false sense of complacency by the media as their freedoms are stripped from them. From the darkness, a collection of underground computer hackers emerges to find valuable secret information which can lead to the downfall of the destructive forces that have taken over the planet. YOU are one such hacker.

    Charlotte's Utilities

    Charlotte's Utilities mod for Minecraft Forge made by Sharshar

    Charlotte's Utilities is my first adventure into modding Minecraft. I wanted to have some extra utilities and things for my server that I couldn't find in other mods, or if I could I was able to think of a different way that I would prefer to implement them. At its core, this mod pack is just a collection of utilities that I feel improve the game experience. Everything is fully configurable in the config file so you can change, enable, or disable whatever you feel is best for you! The mod has quickly developed into one that's aimed primarily at the builders of the Minecraft community, and I plan to expand on that idea going into the future. My goal is to provide new, unique, and easy ways to allow players to construct whatever comes to their mind. I take feedback very seriously and if you have a good idea I won't hesitate to implement it. Development of Charlotte's Utilities is made possible by Full Effect Hosting
