The map can be opened with the following console command:
There is a NPC that spawns within the map, that utilises the loadout at the very top position of your loadouts. There are a number of default controls that let you manipulate the attacks that this dummy NPC will input.
|Numpad 1||Change Alt Mode|
|Numpad 3||Lean Forward (Increments)|
|Numpad 5||Switch to Fists|
|Numpad 9||Lean Backward (Increments)|
As a note, if any of these keys are bound/set for any other game control, it will interfere with this functionality.
