AttackOnMine

Mod adds Vertical maneuvering equipment and sword from Attack on titan

The sword has two modes: the first one allows you to detach the blade and the second switches to flight control. You change modes using the "R" key. Additionally, regardless of the mode you are in, holding the shift key and clicking the right mouse button while wielding the thunder spear will allow you to fire it. To reattach the blade, you must have the blade change mode enabled and have the blade in your inventory. Upon clicking the right mouse button, the blade will be reattached.

To make gas used in the Omni-directional mobility gear, you'll need ice found on ice biomes and you have to have a machine called "gas generator" and fuel it with coal. Then, you must wait until the gas is made and fill it either directly into the vest or into the tank.
