Notes

Important note about teleport options: Don't try to teleport from far distance as the game might fail to load the textures properly and you might end up in thin air.

Important note about inventory editor: When you use 'Refresh Inventory Editor' to refresh the editor with new values they will show up in chaotic order meaning what you see on screen might not correspond to slot number and editor includes the whole inventory including but not limited to gears and items such as 'Logan's Chram' or 'Crow Doll' and it's up to you which one to edit whether be it consumables or non-consumable ones.

Refresh Inventory Editor:
Flip this to refresh the inventory editor with new values.

Rapidfire:
This option might not work if you don't have a completely upgraded weapon so either upgrade your weapon or simply use 'Max Weapon Upgrades'.

Walk Anywhere:
This options let's you walk anywhere you can literally climb the thin air but it might not work in some areas.

Warning: It conflicts with Disable Gravity option.

Disable Gravity:
This option will enable you to stay in the air when you go higher using Hover Player Higher and Hover Player Lower options.

Warning: It conflicts with Walk Anywhere option.

Hover Player Higher:
Hover Player Lower:
Enable Disable Gravity first.
