Bits

Bits[edit]
Bits are the primary run currency used during gameplay.
What Bits are used for[edit]
Bits are spent in-run on:
- Upgrade increase levels (the in-run upgrade button upgrades)
- Modules (buying/slotting module upgrades in combat)
Bits are not the same as Coins:
- Bits = run currency (combat progression)
- Coins = meta/shop currency (persistent progression)
How you gain Bits (in a run)[edit]
Main sources:
- Enemy kills (base enemy bit rewards)
- Cash Per Enemy and Cash Per Wave upgrade effects
- Bits Worker active generation (if slotted)
- Boosts / Modules / Executables / Lost Packet multipliers affecting bit gain
- Starting Bits at run start (from Starting Bits Download)
Run start baseline:
- You start with base Bits + Starting Bits bonus.
Stored Bits (important)[edit]
There is also Stored Bits (persistent between runs), shown in menu/game as a separate stash.
Current logic:
- Stored Bits are mainly generated by Bits Worker idle value (offline worker gain)
- At the start of a run, you can press Use Stored Bits (available for ~first 30 seconds)
- Using it adds stored Bits to your current run Bits and then resets stored Bits to 0
Bit spending behavior[edit]
- Spending checks affordability (`bits - cost >= 0`)
- Costs scale by upgrade/module formulas
- Bulk buy options (`1x`, `10x`, `100x`, `max`) respect current Bits
Practical tips[edit]
- Early run: invest Bits into core scaling upgrades first (Damage/Health/economy flow)
- Use Stored Bits immediately in hard pushes for faster snowball
- Keep Bits Worker slotted often if you want stronger Stored Bits income over time
