Seasons bring major shifts you need to adapt to for best results. Winter's gonna slow you down with snow drifts and frozen water paths, so plan routes carefully when moving between objectives. During stealth your best friend is gonna be prone crawling through whatever vegetation remains, and keeping an eye out for those frozen ponds that block your usual escape routes.

Guards change up their patterns based on weather which is actually pretty interesting, they'll huddle near fires when it's cold making them easier to predict. Spring and summer give you way more plant cover to work with, and stormy weather helps mask your movement sounds but watch out for reduced visibility yourself.

Tip: environmental kills work differently each season like using icicles in winter for silent takedowns, or taking advantage of summer rainstorms to mask your approach. When seasons change naturally through story progress and fast travel youll find different patrol patterns and fresh loot spots to work with, so its worth revisiting areas you've already cleared to find new opportunities.
