Seasonal Enemies
Frostbanes, Snow Leopards, and Wandering Yetis each serve a different role. Frostbanes drive daily progression, Snow Leopards reward new clears, and Yetis deliver some of the season's strongest limited rally rewards.
Finish Frostbanes before spending large amounts of Gas elsewhere.
Frost Cores support nearly every major Everfrost upgrade. Missing routine Frostbane rewards can slow the Bio Lab, Virus Resistance, and access to stronger seasonal enemies.

Know what each target is for
Frostbanes
The Everfrost replacement for Boomers and the most dependable routine source of Frost Cores. They should normally receive your first seasonal Gas each day.
- Attack the highest level you can defeat efficiently.
- Complete the active reward counter before other Gas use.
- Check the game counter: the opening week may require 30 kills, then 15.
- Stop when rewards end unless an event gives additional value.
Snow Leopards
Snow Leopards replace normal Zombies. Their greatest value often comes from clearing each newly unlocked level for the first time rather than repeatedly farming an old level.
- Complete Frostbanes first.
- Check for newly unlocked levels after resistance upgrades.
- Use alliance help for difficult first clears.
- Repeat old levels only for an event or specific objective.
Wandering Yeti
A powerful mobile world boss designed for coordinated rallies. Higher levels can provide excellent rewards, but failed attempts and hospital losses can be costly.
- Let strong rally leaders choose the target level.
- Join rallies with a realistic chance of success.
- Watch hospital capacity before repeated attacks.
- Use limited reward attacks on organized alliance rallies.
Do not confuse attacks with reward-earning attacks.
Seasonal counters can vary by week, event, or state rollout. Always check the current in-game counter before using extra Gas or limited Yeti attempts.
What should you attack next?
Attack Frostbanes
They remain the strongest routine progression target.
Claim the first clear
One new clear is usually more valuable than repeating old levels.
Join quickly
Limited successful rallies can provide some of the season's best rewards.
Check active events
Spend remaining Gas where it also scores objectives or seasonal milestones.
Repeating a target after its best rewards are already gone.
More attacks do not always mean more progress. Once the daily Frostbane rewards, new Leopard clears, and valuable Yeti attempts are complete, review the active events before spending additional Gas.
