AVS03 ships 6 bosses and mini bosses per the official Steam page. The count is confirmed; names and patterns await launch verification. What we know, honestly.

The confirmed count: 6

The official store page confirms 6 bosses and mini bosses in the launch build. That’s everything public: the number. Names, arenas, phases, attack patterns and HP are unpublished — and this site’s evidence policy means those sections stay empty rather than fill with invented stats. From September 28, each boss gets its own page here with tested patterns and counters.

How bosses likely frame the game

Two structural facts from the official materials give bosses their shape:

  • Runs last 30–40 minutes — in survivor-likes, that arc typically peaks in a run-ending confrontation.
  • The game has 5 protocol difficulty folders (protocols and policies) — difficulty tiers in the genre usually gate or scale their boss encounters.

Both are structure-level observations, clearly labeled as such — not confirmed boss mechanics.

Preparing before the names are public

You can genuinely get ready for bosses today:

  1. Learn the confirmed weapon-status core — Firewall’s Heat, Paint’s Lag, Bubbles’ Infect — in the weapons database and status effects guide.
  2. Understand the build layers in the builds hub — bosses punish one-dimensional setups.
  3. Know your between-run economy — BeanZ and meta upgrades are where boss-wipe recoveries get funded.
