Tracking PUBG datamined skins and public test server (PTS) strings lets players decide whether to reserve PUBG G-COIN or spend on active store rotations. Sourced store announcements from the April 2026 update confirmed the 10-level Cosmic Caliber Kar98k progressive weapon skin, a collaboration with Stellar Blade paired with Event Pass: Xeno Point, and the return of aespa Step Up bundles (PUBG News 9892). Unreleased mechanics tested in test-server builds—such as a 10-to-1 cosmetic trade-up system—demonstrate how game files can change significantly before reaching production.
Confirmed Store Additions: Cosmic Caliber Kar98k and Collaborations
The April 2026 store announcement confirmed the Cosmic Caliber Kar98k Progressive skin and its 10-tier progression path (PUBG News 9892). The progression structure includes:
- Lv. 1: Basic Skin Cosmetics
- Lv. 2: Headshot Kills BattleStat
- Lv. 3: Inspect Weapon Animation
- Lv. 4: Muzzle / Stock Skin
- Lv. 5: Uncommon Skin Cosmetics
- Lv. 6: Killfeed Skin
The final four tiers unlock advanced visual cues: Scope Skin at Lv. 7, Loot Crate Skin at Lv. 8, Rare Skin Cosmetics at Lv. 9, and the Kill Effect at Lv. 10. The Cosmic Caliber Contraband Crate offers a 50% discount on the Open 10 option for the first 10 purchases.
Beside weapon crates, PUBG Studios confirmed a crossover with Stellar Blade, planned in conjunction with Event Pass: Xeno Point (PUBG News 9892). The studio also scheduled the return of aespa collaboration cosmetics via tiered Step Up packs and individual Loot Cache options.

| aespa Step Up Pack - Step 1 | 200 G-Coin | Single purchase per account; prohibited in Belgium and the Netherlands. (PUBG News 9892) |
| aespa Step Up Pack - Step 2 | 800 G-Coin | Single purchase per account; requires completing Step 1. (PUBG News 9892) |
| aespa Step Up Pack - Step 3 | 1,870 G-Coin | Single purchase per account; requires completing Step 2. (PUBG News 9892) |

Players in Belgium and the Netherlands cannot purchase the aespa Step Up or Loot Cache packs due to local loot box regulations. Single Loot Crate packages remain capped at 50 purchases per account using G-Coin or BP.

2026 Development Roadmap: Executions and Challenge Weapon Skins
Stylized melee weapon Executions arrive in the May update according to the PUBG 2026 development roadmap, giving players custom animations to eliminate knocked opponents (PUBG News 9855).
For the second half of 2026, the roadmap details an in-game Challenge system. Instead of standard crate drops, this framework rewards exclusive weapon skins tied directly to player match performance (PUBG News 9855).
PTR Experiments vs. Production: The 10-to-1 Trade-Up System
Test-server data frequently contains experimental mechanics that never reach the live client. On the PUBG PTR, developers trialed a trade-up system allowing players to convert 10 cosmetics of identical rarity into a single item of the next tier (AltChar).
The test model assigned fixed BP fees per tier:
- 300 BP for common item conversions
- 500 BP for classic tier items
- 1,000 BP for special tier items
Exponential scaling meant crafting one top-tier red item required one million base grey cosmetics. Live servers ultimately bypassed the trade-up mechanic in favor of the Workshop, Contraband Crates, and Event Crafting.
Currency Rules and Expiration Limits
Standard purchased G-COIN remains valid for up to five years under platform rules (XPTopup).
Bonus G-COIN from promotional bundles or shop events carries a shorter window, typically expiring within 30 to 90 days. The game client automatically spends the balance closest to expiration first.
Frequently Asked Questions
Can G-COIN purchased for PUBG: BATTLEGROUNDS be used in PUBG Mobile?
No. PUBG: BATTLEGROUNDS on PC and consoles utilizes G-COIN, whereas PUBG Mobile operates on Unknown Cash (UC). The platforms maintain separate account databases and currencies cannot be transferred or exchanged (XPTopup).
What cosmetic features unlock across the 10 levels of the Cosmic Caliber Kar98k?
The skin progression features Basic Skin Cosmetics at Lv. 1, Headshot Kills BattleStat at Lv. 2, Inspect Weapon Animation at Lv. 3, Muzzle/Stock Skin at Lv. 4, Uncommon Skin Cosmetics at Lv. 5, Killfeed Skin at Lv. 6, Scope Skin at Lv. 7, Loot Crate Skin at Lv. 8, Rare Skin Cosmetics at Lv. 9, and a Kill Effect at Lv. 10 (PUBG News 9892).
Do promotional bonus G-Coins expire if saved for future datamined rotations?
Yes. Purchased regular G-COIN remains usable for up to five years, but bonus promotional coins expire within 30 to 90 days. The game client automatically deducts the oldest expiring coins first (XPTopup).
