Anomaly President update v.0.5.1.21 adds two new combat adversaries, quality-of-life additions, and balancing changes as part of the September roadmap rollout.
New Enemies
The Pufferfish brings slow ranged attacks to combat and self-destructs if its posture drops to zero. The Flombie arrives as an additional enemy type designed to disrupt encounters.
Level Adjustments and Quality of Life
Shielded Security enemies are removed from the Media Building levels. Video previews are added for select abilities on the Permanent Upgrade menu, and bus rooms with available upgrades now display yellow text. Controller vibration options are now available in the settings menu alongside a minor Chinese font fix.
Why this patch matters
Version 0.5.1.21 expands the enemy roster while delivering targeted interface improvements and enemy removals based on campaign balance.
