Summer Marathon - Battle Pass

CHEMISTS: Dead Zone · published 10 Jul 2026, 07:59 UTC

All newsPlayers around this dateRead on Steam

Hi everyone, players!
Summer is here, and the game now features its first long‑term Battle Pass — and it’s completely free!

🌞 Summer Marathon — a unique in‑game event

How to get started

  • After making your first save in the game, you’ll need to reload the game — that’s when the event will begin.

  • The event runs automatically. You can check your progress and view the level details in the Pause Menu by clicking the Event button.

🎯 Event mechanics

  • The only requirement is to gain Experience Points.
    The more XP you already have, the faster you’ll level up in the Marathon.

📊 Marathon structure

  • Total levels: 100.

  • Completion condition: Earn the required amount of XP for each level.

  • Level rewards: Available at every one of the 100 levels.

  • Progression: The higher the level, the more XP is needed — and the better the rewards become.

🎁 Rewards

What the rewards include:

  • Common items — these can also be found or purchased in the game.

  • Exclusive items — available only during this event.

  • Once you successfully complete a level, the reward is automatically added to your inventory.

🔫 Exclusive weapons

  • The event features 8 weapon types from the “Summer Marathon” collection. All of them outperform their base variants.

📈 Final rewards for completing the entire Marathon

  • 💰 Cash reward: 755,000

  • ⭐ Reputation points (for various factions): 2,500

  • 🔫 Exclusive weapons: 8

  • 💣 Powerful grenades: 160

  • 🧪 Alloy ingots: 80

  • 📦 Total items (excluding the above): 1,000+

  • 📦 Total weight of items: 404 kg

💡 Why you should participate

  • The event is free and requires no in‑game purchases.

  • Rewards scale with your effort.

  • You’ll get unique weapons that can’t be obtained anywhere else.

  • It’s a great way to boost your reputation and gather crafting resources.



The more you play, the faster you’ll advance through the levels and unlock even better rewards!

I might run events like this every season, with new rewards and conditions.
