Features

  1. Over 100 Unique New Legendary Effects 1.1 Some effects can change the way you approach combat, such as: Shrink Ray: Hits shrink enemies by 75% for 60 seconds?! (Image 1)(Shrunken enemies are more likely to flee and have reduced attack range.) Gravitational: Bashing attack has 33% chance to pull targets towards you. (Image 5) Aniki!: Reduce your damage by 99%. Each hit has a 10% chance to convert the target into an ally follower for 600 seconds.(Image 6) Puppet Show: Killed targets are revived for 60 seconds to fight for you. (Image 8) Parasite: On kill, 50% spawn 1-3 friendly Heatleeches from the target. Always triggers on robots. Has a 1.5% chance to evolve directly into a Terrormorph!

1.2 Some effects are extremely powerful, but come with drawbacks, such as: Slow Motion: Time slows by 70% while holding breath. Oxygen consumption while holding breath is increased by 25%. One Last Kill: Deals 1,000,000 damage, then the weapon is destroyed! Timeways: Gain 50% increased damage and 50% damage resistance. Time flows 50% faster in combat?!

1.3 Some effects improve exploration and convenience, such as: ZeroG: Your gravity is 0. (Image 3) (Space walk everywhere!) Black Hole: Continuously pulls movable objects within a 20m radius. (Image 4) (Never miss loot again!) (Objects can even block bullets for you.) (Vehicles can remain airborne for extended periods.) Z-Train: Time slows by 30% while sprinting. Sprinting while overencumbered slows time by an additional 60%. Hannibal: Human corpses can be consumed to restore 10% Health. Looter: Killing an enemy loots all their equipment and removes the body.

In addition, Fullsuit spacesuits (such as Starborn Spacesuits) can now install all non-weapon Tier 4 effects. Some effects also feature entirely new particle visual effects as indicators.

  1. Reworked Vanilla Legendary Effects Many weak or underwhelming vanilla legendary effects have been significantly improved, including: Bashing: Deals 400% damage and has a 25% chance to disarm targets when gun bashing. Acrobat: -99% fall damage, +100% jump height, and -50% oxygen consumption while jumping. Speedster: Gain 25% Movement Speed. Effect is doubled while overencumbered. Taking damage has a 10% chance to knock down enemies within 5m.

  2. Build Your Legendary Effects You can equip up to 16 different legendary effects at once, creating nearly limitless build possibilities. Below are 4 simple examples of effect combinations.

  3. Think Legendary Enemies Are Too Weak? You can now adjust their strength through a Gameplay Option Setting. (Image 2) Available settings: 0.5x / 1x / 1.5x / 2x / 3x You can freely strengthen or weaken enemy legendary effects depending on your preferred difficulty.

  4. Improved Legendary Effect Descriptions All legendary effect descriptions have been rewritten to remove vague wording. Precise numerical values are now displayed directly, for example: Reckless: Reduce magazine capacity to 1, increase base damage by 400%, and reduce Max Health by 50%. Incendiary: 9% chance to deal incendiary damage.

  5. Fixed Several Vanilla Bugs Fixed multiple vanilla legendary-related bugs. For example: One enemy legendary effect was unintentionally reducing the his health instead of increasing it.
