Black Ice April 2021 Update

Hi everyone! superdupergc here, just wanted to let y'all know what I've done in the past month. This patch is already live!

Highlights
- About 3 dozen new Weapon Skins for Super Duper weapons (which have a small chance of showing up on other items too!)
- Tripled Super Duper item drop rate
- Low Gravity server security
- Minigun and SMG weapon types
- Fire, Ice, Lightning, and Rainbow damage types, each with their own strengths and weaknesses
- Detailed sub-tooltips so you can see exactly what that new affix does
- Per-difficulty mission and world state saves, so each difficulty level is the full experience
- A gorgeous new grid shader which makes spaces easier to navigate
- A dozen new Bounty types, including Multikills, Out of Line of Sight, and Airborne
- AI Upgrades for the Bats and Minions
- Lots of item balancing, in particular for Heals, Minions, Scopes, and Exploits.
- Tons of bugfixes

I think you're going to like this update! I'm starting work on the new progression screen today, and Nonadecimal's been working on the Act 2 finale tower!

Enjoy!
