ULTRA RAIN

All 97 of Risk of Rain 2's base-game items in ULTRAKILL. You play ULTRAKILL; the items' icons, names, descriptions and pickup sound are read from your own Risk of Rain 2 install while the game runs. Nothing from either game is shipped with the mod.

What you get

• Cyber Grind runs: after every wave, three Risk of Rain 2 items float in front of you. Touch one to take it; the other two vanish. Items stack the way they do in Risk of Rain 2 and reset when the run ends.
• Campaign drops (optional, off by default): turn on CampaignDrops and enemies in the campaign have an 8% chance (CampaignDropChance) to drop an item.
• Every base-game item: 24 white, 25 green, 21 red, 14 lunar, 13 boss, each rebuilt for ULTRAKILL. Every banner shows Risk of Rain 2's own text plus an "In ULTRAKILL:" line saying what it does here. How Risk of Rain 2 ideas map onto ULTRAKILL:
  • gold is style points; a teleporter event is a Cyber Grind wave
  • sprinting is sliding; equipment use is a parry; skill cooldowns are weapon charges and dash stamina
  • elites are Radiant enemies; max health is a bonus health pool on top of your 100, with shield and barrier
  • allies (Queen's Gland, Happiest Mask, Empathy Cores, Halcyon Seed, Squid Polyp) float beside you and shoot
  • the Heresy items add lunar powers to the revolver, whiplash, dash and parry, each with a drawback
  • Dio's Best Friend brings you back at full health instead of dying
• The Risk of Rain 2 pickup moment: the real item pickup sound, a banner with the item's icon, name and description, and an item bar with stack counts across the top of the HUD.
• Single player. ULTRAKILL has no multiplayer.
• Leaderboards stay clean: Cyber Grind scores are not submitted while the mod is installed, and level scores are not submitted while campaign drops are on.

DLC items (Survivors of the Void, Seekers of the Storm and later) are not included: their files are in every Risk of Rain 2 install, but a mod inside ULTRAKILL cannot tell whether you own them.
