Requirements

ULTRAKILL must be installed on the same PC. The mod loads V1's models, sounds and effects from your own ULTRAKILL install; nothing from ULTRAKILL is included in this package. If ULTRAKILL isn't found through Steam, set its folder in the config (General > UltrakillPath).

ULTRAKILL sounds

Risk of Rain 2 ships with Unity's audio engine switched off, so the mod switches it on (before the game starts) to play ULTRAKILL's sounds. This flips one setting in Risk of Rain 2_Data/globalgamemanagers (a backup is kept). To turn it off, set General > EnableUltrakillAudio = false in the config; that restores the original setting.

Default controls

V1's skills use Risk of Rain 2's normal skill keys, and its extra ULTRAKILL keys use ULTRAKILL's defaults. Everything can be rebound in the game's Controls menu (the V1 keys are listed under Jump).

Key	Action
Left Mouse	Fire the current weapon (Primary)
Right Mouse	The current weapon's alt fire (Secondary)
Left Shift	Dash (Utility)
R	Whiplash / Spiked Whiplash (Special): hold to throw, release to pull
Space	Jump (wall jump against a wall)
Left Ctrl	Slide on the ground, ground slam in the air
F	Punch
G	Switch arm (Feedbacker / Knuckleblaster)
1 – 5	Revolver, Shotgun, Nailgun, Railcannon, Rocket Launcher; press again to cycle that weapon's variants
Mouse Wheel	Next / previous weapon
V	Toggle first / third person
E	Interact
Q	Use equipment

Shop terminal: walk up to it and V1 puts its guns away; aim at the screen and click Left Mouse to buy and swap weapons.

Config

The config file is com.sethly.rouk.cfg (edit it in r2modman under Config editor). V1's extra keys (punch, switch arm, slide, weapon slots, camera toggle) are rebound in the game's own Controls menu instead.
