Bitlings, Capsules and the Bytedex
There are 25 Bitling families across 8 types: Volt, Pyro, Aqua, Ice, Toxic, Cloud, Glitch and Crypt. You start with Voltbit, Embit or Dropbit, and catch the rest in capsules. Duplicates add stars that make a Bitling stronger, and you can train each one with coins. Fill the Bytedex by evolving them in battle.

Tips
- Focus your build. Leveling two or three attacks to 5 beats many weak ones.
- Pick attacks of your Bitling’s type: each one gives +8% damage to everything.
- Take a healing utility such as Auto-Update, Repair Kit or Data Siphon before wave 8.
- Use the walls to block snipers and bullets.
- Hunt elites and vaults. They drop chests and capsule tickets.

How do Bitlings evolve?
During a run, your Bitling evolves at level 8 and again at level 18. Each evolution makes it bigger and stronger, and the final form also evolves its signature attack. Legendary Bitlings do not evolve but start very strong.
