How to Open Crates in Combat Arena
Crates are Combat Arena's primary cosmetic loot system. They roll weapon skins, charms, camos, and rare collectibles from themed collections without affecting core gun stats. You receive crates from promo codes like JUSTFORFUN, milestone rewards, events, and direct shop purchases. This guide explains how to open them, what each crate type contains, and when opening crates makes sense relative to spending coins on weapon unlocks.
What Are Crates?
Crates are inventory items that reveal random cosmetics when opened. Unlike weapon unlocks from the armory, crate contents are cosmetic-only — they change appearance, not damage or fire rate. Collections include Primordial, Street, and Frostbite sets detailed on the crates overview page, each with distinct visual themes and rarity tiers.
- Primordial Crate — Ancient-themed skins often tied to milestone codes.
- Street Crate — Urban camo and street-style weapon finishes.
- Frostbite Crate — Ice and winter cosmetics from seasonal events.
How to Open a Crate Step by Step
- Launch Combat Arena and open the main menu.
- Navigate to Inventory or Crates — label varies by UI update.
- Select the crate you want to open from the list.
- Confirm the opening animation and review the rolled item.
- Equip the new skin from the loadout or armory cosmetic tab.
Crates from codes redeem through the same account-wide inventory as match drops. Redeem promos using the code guide, then open crates immediately so you do not forget them in inventory after sessions.
Getting Crates for Free
The fastest free crate income is promo codes on our active codes list. Historical codes like those archived on the expired page granted Street and Frostbite crates — watch official Atomic Horizon announcements on the community page for similar drops after updates tracked on the updates page.
Event challenges and login rewards occasionally grant crates without codes. Play during patch weekends when developers celebrate concurrent player milestones — those windows historically include bonus crate handouts alongside coin boosts discussed in the coins guide.
Crates vs Weapon Unlocks — Spending Priority
Coins are finite early game. Unlock combat-effective weapons before mass-opening crates. Follow the weapon unlock guide and tier list until your loadout covers close, mid, and optional long range. Once your loadout is stable in TDM and FFA, redirect surplus coins toward crates or direct skin purchases on the skins page.
| Spending Priority | Stage | Reason |
|---|---|---|
| Weapon unlocks | Early | Raises win rate and XP speed |
| Scorestreaks | Mid | Information advantage in fights |
| Crates | Mid-late | Cosmetics after combat kit is ready |
| Duplicate farming | Late | Collection completion only |
Understanding Rarity and Duplicates
Each crate roll pulls from a weighted pool — common camos appear frequently while legendary finishes are rare. Duplicate cosmetics may convert to coin shards or duplicate credits depending on current Atomic Horizon rules shown in-game at open time. There is no guaranteed pity timer advertised publicly, so treat crate opening as cosmetic gambling with coins you can afford to lose.
Equip new skins immediately to verify they fit your preferred weapons. A Frostbite sniper skin matters only if you actually run snipers from the sniper tier list on open maps listed in the maps guide.
Opening Crates After Codes
When you redeem a code granting a Primordial or Street crate, open it before your next ranked session if the rolled skin applies to weapons you main. Cosmetic hype is fun, but a new camo on your MP5 or M4A1-class primary pays off faster than a skin for a gun you never purchased.
- Redeem code → confirm crate in inventory → open → equip on active loadout.
- Screenshot rare pulls if you share with friends — not required for gameplay.
- Never trade accounts or buy crates from strangers; scams target cosmetic hunters.
