Introduction
Scrap Exchange is a time-limited event where players complete missions to earn a special currency called Scrap Tokens. These tokens can be exchanged for valuable rewards in the Merchant Shop. The event connects combat gameplay with a trading system, allowing players to earn and redeem rewards through active play.

Who can participate?
All players who have unlocked the required game features and combat modes can participate in the event. Specific access conditions may vary depending on the event run configuration.

How does it work?
During the event, players complete various missions to earn Scrap Tokens.

Missions may include objectives such as:
- Winning fights
- Destroying enemy weapons
- Participating in gang fights
- Fusing parts

                               
Each completed mission grants Scrap Tokens automatically. Tokens can then be spent in the Merchant Shop on available rewards.


Do I need to make a purchase?
No. Purchases are optional. Players can earn Scrap Tokens entirely through gameplay missions. However, optional offers such as Gem Bundles or Token Boosters may be available for players who want to progress faster.

What rewards can I get?
Scrap Tokens can be exchanged in the Merchant Shop for a variety of rewards, such as:
- Coins
- Gems
- Toolboxes
- Premium Part Packs

Shop inventory may refresh during the event or follow a preset schedule. Some rewards may have limited quantities depending on the event configuration.

Why are some missions difficult?
Certain missions are designed for highly engaged or advanced players. These missions may require more battles, stronger builds, or higher activity levels. They are optional and provide additional earning opportunities.

How is progress counted?
Mission progress updates automatically as you play. When a mission is completed, Scrap Tokens are credited instantly, token balances update in real time, and completion feedback appears on screen. Rewards purchased from the shop are delivered immediately.

How long does the event last?
The event duration varies by run but typically lasts between 3 to 5 days. Exact start and end times are displayed in‑game.

What happens when the event ends?
When the event timer expires, the Merchant Shop closes and all remaining Scrap Tokens expire. Unused currency cannot be carried forward, so players should spend all tokens before the event ends.
