In this mod you will have the opportunity to do amazing things, such as: run fast, swim fast, climb ladders fast and do longs jumps. In addition, you will be totally immune to physical damages and still have special powers, 8 in total. But you will need a certain amount of energy to do the special powers. This energy, will be your ARMOR bar and it will regenerate slowly.
