What Is the Secret Cache System in Season 2?
The new Secret Cache system is accessed through the Events tab, where the Cache Tracker now shows expanded progression details. Season 2 introduces a new AK-47 Legendary path, which means Secret Caches can now drop AK-47 shards, with 200 shards needed to unlock the weapon. The Cache Tracker currently includes:
Power Nova camo progression
Two free Legendary weapons
One free Mythic weapon
AK-47 Legendary shard tracking
Universal shard and exchange access
Unlike limited-time lucky draws, this system is designed for slow, guaranteed progress. COD Mobile has confirmed that the Mythic weapon will remain the same for the entire year, making shard management more important than ever.
How to Earn Secret Caches Daily
Earning Secret Caches in Season 2 is still very accessible, even for free-to-play players.
Daily Challenges - Completing daily challenges rewards three new Secret Caches per day. Players only need to:
Play three matches.
Wins are not required.
Free-for-All matches usually last around two minutes per game.
That’s under 10 minutes a day for guaranteed progress. This makes the new Secret Cache system one of the most casual-friendly grinds in COD Mobile.
In the second column of your daily routine, many players also choose to safely top up their Battle Pass or COD Points using LootBar, a popular platform among COD Mobile players for smooth transactions and quick access. Check it out now!
Battle Pass & Challenge HQ - Additional caches can be earned from:
Free Battle Pass tiers
Premium Battle Pass tiers
Challenge HQ objectives
Token Pass milestones
Even without spending money, players can stack a large number of caches throughout the season. Need COD Points fast? Use LootBar for a clean and simple top-up experience.
Secret Cache Types, Upgrades, and Drop Changes
Most Secret Caches still begin as Epic (Purple), but Season 2 significantly improves what happens when duplicates drop.
Upgrade Chances - Each cache gives three upgrade attempts:
1% chance: Epic - Mythic (Red)
15% chance: Epic - Legendary
25% chance: Legendary - Mythic
These odds haven’t changed, but what happens after opening has improved for a good part.
What Changed in Season 2?
Old Mythic caches now drop tokens only.
Old Epic caches convert duplicates into universal shards, not wasted tokens.
Duplicate rewards now give Mythic, Major Legendary, or Minor Legendary shards.
All of this means saved caches are no longer useless: opening them gives real progression value.
Shard Exchange System
Season 2 introduces the Shard Exchange tab, one of the most requested features in the COD Mobile history.
Exchange Ratios
First 30 shards per season: 1 token = 1 shard
After that:
2 tokens = 1 shard
3 tokens = 1 shard
This system reduces abuse while still rewarding consistency.
Major vs Minor Legendary Shards
Minor Legendary shards: Melee Mythic items
Major Legendary shards: Weapons like AAX
These shards are specific with item, not interchangeable. This explains the reason some weapons were easier to unlock than others in previous seasons.
Limitation: You cannot exchange shards for the current AK-47 yet. New items must be fully worked through the new Secret Cache system before becoming eligible for exchange after removal.
Best Strategy for Season 2 Secret Caches
To maximise progress, efficiency matters more than volume. The recommended strategy includes:
Never miss daily challenges.
Use all three upgrade attempts.
Open old Epic caches first.
Exchange only 1:1 shards when available.
Spend tokens before the seasonal reset.
Exchange Store Priorities
Gold Coupons (best long-term value)
Secret Caches
Stealth Chopper skin (self-paying via challenges)
Avoid cosmetic-only items until shard goals are complete.
For players who still prefer topping up for convenience, LootBar remains a trusted option for COD Mobile purchases. Don’t miss out on this.
Important Season 2 Warnings and Tips
Tokens reset each season.
Clan War currency also resets.
Old Epic caches are valuable: do not ignore them.
Hardcore grinders may temporarily stockpile unusable shards.
Always check Wednesday updates for exchange changes.
Missing exchanges means losing progress permanently.
Conclusion
The Season 2 update transforms the Secret Cache system into the most rewarding free progression feature COD Mobile has ever introduced. With the addition of shard exchange, AK-47 tracking, and improved duplicate handling, players now have far greater control over how their time and effort convert into real rewards.
While the system still values patience, it clearly respects player commitment and consistency. By playing daily, managing shards carefully, and exchanging rewards before seasonal resets, steady progress is guaranteed.
There is no need to spend COD Points or grind endlessly in long sessions. Simply logging in, completing straightforward challenges, and making smart upgrade decisions is enough to stay on track throughout the season.
What truly sets the new Secret Cache system apart is its long-term value. It offers something rare in mobile shooters: a reliable path to Legendary and Mythic rewards without relying on luck. Whether you are a casual player or a devoted grinder, the system rewards planning, efficiency, and persistence.
If you’re grabbing the Battle Pass or COD Points, LootBar is a simple and reliable platform. With consistent effort and smart resource management, Legendary and Mythic unlocks become a matter of time, not chance.
